Workshop and fieldtrip to the Awaynat Wanin Area of the Southern Ghadamis Basin, Libya, April 23 - 30, 2008
A workshop and field trip of the International Geoscience Programme (IGCP) project 499 entitled “Devonian Land –Sea Interaction: Evolution of Ecosystems and Climate” (DEVEC) was organized between April 23rd and 30th in Tripoli, Libya.
A one day symposium in Tripoli was followed by a field trip to the Awaynat Wanin Area of the Southern Ghadamis Basin, west of Libya. The excursion, which was guided by Jean-Noel Proust, CNRS, Universite de Renne, and Milad Ben Rahuma, Libyan Petroleum Institute (LPI), attracted participants from Australia, Czech Republic, France, Germany Libya, and U.K.
The workshop and the field trip were devoted to the stratigraphic evolution of Devonian sequences in the Awaynat Wanin area, Southern Ghadamis Basin with a focus on sequence stratigraphy, sedimentology and facies, and palaeoecology. The Devonian of Libya is of special interest for the project due to the excellent sequences mainly representing very shallow water environments and even fluvial sequences. The workshop was initiated at the Libyan Petroleum Institute (LPI) in Tripoli with an opening ceremony, which includes the welcoming adresses by the General manager of LPI, Dr Bourima A. Belgasem, and the coordinator of the meeting, Dr Ali D. El Mehdawi. After introductory remarks on the IGCP 499 project, its objectives and results within the last four years by Dr Peter Königshof a key note presentation by Bashir Elmejrab, Shell EP Libya GmbH, on the Geology of the Ghadamis Basin was given.
The workshop and the field trip were to familiarize the participants with an introduction to the stratigraphy and sedimentology of the Palaeozoic sequences in the Southern Ghadamis Basin which is one of the major Palaeozoic basins in Libya. A 43-page abstract volume and an 67-page filed guide book have been published, edited by Milad Ben Rahuma, Jean-Noel Proust, and Remi Eschard.
In the morning of the second day the party went to the Awaynat Wanin area, a trip of more than 500 km to the southwest of Tripoli crossing the impressive region of Hamada Al Hamra. On the way to the south, the wonderful cliff exposures of Mesozoic series of the Sirt Basin have been visited. Participants arrived in the field camp in the late afternoon and were introduced to the regional Geology.
The Ghadamis Basin is located in the northwestern part of Libya and extends westward to Tunisia and Algeria. During the Palaeozoic, the North African Platform was divided into several basins and arches. The basins underwent a slow subsidence whereas the arches were periodically eroded due to uplift and/or eustatic sea-level falls. The sedimentological framework of these intracratonic basins were controlled by very low sedimentation rates, resulting from erosion of the tectonic arches. Sediments are mainly composed of siliciclastics, such as sandstones, claystones, and shales, representing a broad variety of depositional environments ranging from proximal fluvial to offshore marine facies (Ben Rahuma et al. 2007). Devonian rocks in the Southern Ghadamis Basin have been subdivided into four formations, namely the Tadrart-, Ouan Kasa-, Awaynat Wanin-, and Tahara Formation. These formations exhibit distinct layers of fauna and flora, which have been described ealier (e.g., Massa 1988; Gundobin 1985).
The following morning of April 25th, the party went to the sections exposed in the Awaynat Wanin area. This day was devoted to the Upper Ordovician Mamuniyat Formation representing estuarine mouth bars deposits, overlain by the Tanezzuf Formation which contains various graptolithes and is interpreted as an open marine environment. The latter formation is overlain by the Lower Devonian Tadrart Formation. In the Awaynat Wanin outcrop area the Tadrat Formation is characterized by rare trace fossils, such as Planolites, Nereites ichnofacies, Diplocraterion, and Skolithos. At the end of the day the participants studied the next younger section representing the Lower part of the Ouan Kasa Formation. The variety of sandstones, siltstones and claystones with characteristic sediment structures such as, flaser bedding, channel fill deposits with abundand mud clasts, represent lower shoreface to upper shoreface and tide-influenced depositional settings. This interesting day was finally concluded in the afternoon with general discussions on the sections, while relaxing with perfect service by our hosts.
The next day was devoted to Lower- to Middle Devonian (Emsian to Givetian) sequences (Ouan Kasa Fm, Awaynat Wanin I Fm, Awaynat Wanin II Fm) which are dominated by shoreface ond offshore marine deposits with rare fluvial intercalations. The offshore shale within the Awaynat Wanin I Formation is an equivalent to the Eifelian Emgayat Shale in the subsurface of the Ghadamis Basin and has hydrocarbon significance as a seal rock for the Lower Devonian reservoirs. Within these sequences frequent brachiopods and bivalves occur. A variety of ichnofabrics such as Diplocraterion and Skolithos are abundant and many plant remains occur.
The subject of the next day in the field was devoted to the Middle- and Upper Devonian in the Awaynat Wanin area (Awaynat Wanin II Fm to Awaynat Wanin IV Fm, and Tahara Fm). Beside the sedimentological and sequence stratigraphic features, one of the most interesting part within this sequence are the iron-ore nodules of different size, ranging from few centimeters to about 1.5 meters. It is still unclear whether these red beds and nodular concretions. represent a palaeosoil or a condensed horizon, or if these deposits represent reworked iron-oolite beds or pressure-solution diagenetic evolution of organic-rich sideritic shales. The problem concerns also the exact age of these horizon close at the Frasnian/Famennian boundary.
The days in the field were finally concluded after dinner. Evening meetings and discussions were held in the “workshop tent” to summarize the main results of the day. A final meeting was held at the April 27th 2008 to discuss the achievements and outcome of the field meeting.
On April 28th, the participants went back to Tripoli and along the way a stop was made to investigate highly biotubated sediments of the Upper Cretaceous. The last day of the field meeting was devoted to the fascinating anchient city of Leptis Magna. The city appears to have been founded by Phoenician colonists around 1100 BC, although it didn't achieve prominence until Carthage became a major power in the Mediterranean Sea in the 4th century BC. Later it became a part of the Roman Empire. Leptis Magna has been partly excavated under the auspice of UNESCO. For the participants also the last day was perfectly organised and we all got an idea on the living conditions and the culture of the people during the Roman empire.
For all participants – especially those from foreign countries – the workshop and the accompanying field trip offered a unique opportunity to get an insight into the sedimentology, facies, sequencestratigraphy and palaeoenvironmental interpretaion of the Devonian sequences of the Southern Ghadamis Basin and to compare them with other sequences which have been investigated wordlwide in the framework of the IGCP 499. Relationships of regional geological features, the correlation with other areas worldwide and open questions with respect to biostratigraphy, facies interpretation and depositional environment, generated vivid discussions in the field and during evening discussions and helped identify topics requiring future research. One of the main advantages of the field trips was the presence of scientists representing different disciplines. Therefore, the workshop will act as a catalyst for future collaborative research between groups in and outside Libya, as well as offering a network for collaboration between researchers involved in the IGCP 499.
The common efforts of the Libyan colleagues produced a successful event in Tripoli. Moreover, the workshop was organized in an attractive area, both scientifically and naturally, of fine sections, within a spectacular landscape and, what is most important, attracted a good range of colleagues (Fig. 5). The IGCP 499 project is a UNESCO-IUGS sponsored project and on behalf of the organizers and the project leaders we would like to thank all the participants for their valuable contributions during the scientific meeting and the field trip. Cordial thanks are expressed to the local specialists for the organization and guidance of the field trip. We are grateful to these and many other individuals who helped make the workshop both successful and highly enjoyable. Special mention is also made of the following companies and institutions for sponsoring: Libyan Petroleum Institute (LPI), German Science Foundation (DFG), German Federal Foreign Office, Senckenberg Research Society and Natural History Museum.
Joint IGCP 499 / SDS Meeting “Rapid Global Change in the Devonian”, Subcommission on Devonian Stratigraphy and IGCP 499 Devonian Land Sea Interaction Nevada, USA, September 09 – 18, 2007
As in previous years, a joint meeting of IGCP 499 and the Subcommission on Devonian Stratigraphy (SDS) was held in fall 2007 in Nevada. The successful conference and field trip brought together scientists engaged with the Devonian from all over the world. Three days of technical sessions took place in the historical Opera House of Eureka, Nevada. A pre-conference field trip led to sections spanning most of the Devonian in north eastern Nevada and western Utah. The meeting in Eureka was very well-organized by D.J. Over, Dept. of Geological Sciences, SUNY Geneseo, New York, and J. Morrow, Dept. of Geological Sciences, San Diego State University, California. The field trip was perfectly arranged by Jared Morrow and the co-leaders C.A. Sandberg, J.E. Warme, M.A. Murphy, and D.J. Over.
The meeting in Eureka was attended by about 45 colleagues from 11 countries who presented 40 oral and 12 poster contributions which covered the whole array of Devonian research topics. Among those papers dealing with sea-level changes and/or cyclic sedimentation, stratigraphy, regional geology, palaeontology as well as land-sea interactions were strongly represented. On September 17 the annual SDS meeting was held, followed by a business meeting of IGCP 499.
The six days field trip, representing an essential part of the entire conference, started in Las Vegas on September 9. Outcrops of various Devonian successions and local areas were demonstrated, highlighting some of the classical as well as recently investigated sections.
The field trip route within the Great Basin region (Basin and Range province) covered primarily carbonate shelf settings including reefs, and slope to basinal deposits of different areas such as the Confusion Range and Burbank Hills in Utah, Lincoln County and Antelope Range in Nevada. Special attention was paid to the impact related Alamo Breccia (very well exposed in the Hancock Summit West and Mount Irish) and to several sections spanning the Frasnian/Famennian boundary (besides others the classical locality at Devil’s Gate near Eureka). Furthermore, Lower to Middle Devonian strata including the Silurian/Devonian boundary were demonstrated. It was especially impressive for the participants to visit sections introduced by some of the pioneers of western US Devonian research.
The attendees were provided with an abstract volume and a perfectly arranged field trip guidebook (references see below). Further information can be obtained from the websites of IGCP 499 (www.senckenberg.de/igcp-499) and SDS (www.unica.it/sds).

Field Workshop of IGCP 499 San Juan, Argentina, May 14 – 22, 2007
A field workshop of the International Geoscience Programme (IGCP) project 499 entitled “Devonian Land –Sea Interaction: Evolution of Ecosystems and Climate” (DEVEC) was held between May 14th and 22nd in San Juan, Argentina.
The Devonian of San Juan and Mendoza Precordillera, and the San Rafeal Block are of special interest for the project due to the palaeogeographic and biostratigraphic importance in the Devonian Malvinokaffric Realm, but also in the tectono-sedimentary evolution of the Precordillera terrane.
A two-day symposium in San Juan was followed by excursions to Western Argentina covering stratigraphic sequences from Early to Middle Palaeozoic. The workshop was organized by colleagues of the Facultad de Ciencias Exactas, Fisicas y Naturales, Universitdad Nacional de San Juan, Instituto de Geologia “Dr. Emiliano Pedro Aparicio (INGEO), Instituto Superior de Correlacion Geologia (INSUGEO), of the Facultad de Ciencias Naturales e I.M.L. Universidad national de Tucuman, Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET). The workshop was designed to provide participants with an introduction to the diverse and tectonically complex geology in the Precordillera of the San Juan and Mendoza Provinces, besides of the San Rafael Block. The symposium was initiated with an opening ceremony, which includes welcomming addresses by the Dean of the National University of San Juan, MSc. Jorge A. Sisterna, and by one of the organizors, Dr. Silvio Peralta. Dr. Peralta also presented an overview of the regional geological setting and gave an introduction to the outcrops provided by fieldexcursions. Dr. Peter Königshof gave a short overview on the new IGCP guidelines and on the past activities and future perspectives of IGCP 499.
The second day included oral- and poster-presentations with a special focus on facies development in different palaeogeographical settings as well as stratigraphy, sedimentology, and biodiversity of the Devonian in Argentina an elsewhere. Field excursions were preceded by scientific sessions held at the National University of San Juan. An 120-page abstract volume and a field guide book was published, edited by Guillermo Acenolaza, Maria del Milagro Vergel, Silvio Peralta, and Rafael Herbst.
In the afternoon of the second day the party went to the first outcrops nearby San Juan, to investigate the Cambro-Ordovician platform sequences.
The following morning of May 16th geoscientists from Argentina, Bulgaria, Czech Republic, Germany, and Tukey drove to the Talacastto Creek to see localities of the Early Ordovician carbonate sequence, Late Asgill-Silurian deposits and shallow water Devonian siliciclastics. The next day was devoted to the Don Braulio - Rio del Alto section in the Eastern Precordillera at the Don Braulio Creek where sequences from the Lower Ordovician-Devonian have been studied in detail. This interesting day was finally concluded in the afternoon with general discussions on the sections, while relaxing with the famous Argentinian wine and excellent prepared beef, called Asado. At 6am of the next day the field party travelled to Mendoza Province to visit for the next two days sections which belong to the San Rafeal Block. Along the way to the south participants could get an overview on the structural geology of that area and the fascinating landscape as well as on the younger volcanic rocks of Upper Permian to Triassic age. The Silurian-Devonian Rio Seco de los Castanos Formation in the San Rafael Block and the overlying Carboniferous succession raised several questions related to their tectonic setting, sedimentary environment and genesis. The contact to the Carboniferous deposits has been interpreted as an angular discordance based on other sections which show similar structures. It seems reasonable that the Devonian siliciclastics which are several hundred meters thick represent a muddy platform delta-system. After the two days in the San Rafael Block, the group went back to San Juan. The following day (May 20th) the participants travelled again to the south to see the San Isidro section, west of Mendoza City, which is a classical locality within the Central Precordillera. A special focus was on sequences from the Early Palaeozoic up to the Early-Middle (?) Devonian. The Lower to Middle (?) Devonian sequences are of special interest due to their synsedimentary framework and it seems obvious that these olistostrome deposits are related to strike-slip tectonics.
The subject of the last day in the field was devoted to Early Palaeozoic up to Devonian sequences of the western part of the Central Precordillera and Western Precordillera. Outcrops were visited in the La Invernada Range and in the Rio Jachal area. The participants examined those rocks which exhibit several differences in comparison to the Eastern Precordillera and the eastern part of the Central Precordillera. For many participants – especially those from foreign countries – the workshop and the accompanying field trip offered an unique opportunity to get an insight into the complex Devonian Malvinokaffric Realm of the Precordillera, Mendoza region, and San Rafael Block. Relationships of regional geological features and open questions with respect to biostratigraphy, facies interpretation and depositional environment, generated vivid discussions and helped identify topics requiring future research. The workshop will act as a catalyst for future collaborative research between groups in and outside Argentina, as well as offering a network for collaboration between researchers involved in the IGCP 499.
The common efforts of all the above mentioned organizations and specialists produced a successful event in San Juan, Argentina. Moreover, the workshop was organized in an attractive area, both scientifically and naturally, of fine sections, within a spectacular landscape of the Precordillera and the Andes and, what is most important, attracted a good range of colleagues. On behalf of the organizers and the project leaders we would like to thank all the participants for their valuable contributions during the scientific meeting and the field trips. Cordial thanks are expressed to the local specialists for the organization and guidance of the field trip. We are grateful to these and many other individuals who helped make the workshop both successful and highly enjoyable. Special mention is also made of the following companies and institutions for sponsoring: UNESCO/IUGS, German Science Foundation and German Federal Foreign Office.
IPC 2006, June17-21, 2006, Beijing, China
A session (T7) on Devonian land-sea interaction: evolution of ecosystems and climate was held on June 17, 2006 in conjunction with the International Palaeontological Congress (IPC) in Beijing, China.
The successful and enjoyable session (21 oral and poster presentations) took place in the Yingjie Conference Centre. There was a large positive response to our call, and the convenors of the session (Peter Königshof and Xueping Ma) could welcome more than 30 colleagues from Australia, Canada, China, European countries and the USA. Far more talks were offered than could be accommodated in the single-session programme. Finally 15 talks on a wide range of topics with numerous new data and stimulating scientific ideas, e.g. on carbon isotop stratigraphy, climate fluctuations, sedimentology and microfacies, palaeoecology and mass extinction events were presented. The abstracts of the contributions to the T7 session are published in the IPC abstract volume (Qun Yang et al. (eds.): Anchient life and modern approaches – Abstracts of the Second International Palaeontological Congress. University of Science and Technology of China Press; 1-553). All in all, the IGCP 499 session was highly successful: it brought together people from a wide range of countries and experience in various disciplines. The organisation of an International Conference would not have been possible without the support and help of numerous people and institutions. The Chinese colleagues and their students have to be thanked for organizing and hosting an interesting conference. The topical session was partly supported by the German Science Foundation (DFG).

IGCP-499 Workshop „Depositional Environments of the Gondwanan and Laurasian Devonian”, Istanbul, Sept. 26 – Oct. 3, 2005
The Devonian of Turkey is of special interest because it is comprising Laurasian and Gondwanan components on different tectonic blocks. Therefore, an active group of Devonian researchers was assembled in Turkey by co-leader M. N. Yalcin to work on the goals of IGCP-499. This was the reason to held a workshop on „Depositional Environments of the Gondwanan and Laurasian Devonian” in Istanbul from Sept. 26 – Oct. 3. The workshop was attended by about 50 colleagues, mainly from Turkey, but also from Bulgaria, Germany, Lithuania, Morocco, and the USA. There have been about 20 oral contributions and several posters covering major aspects of the subject with a special focus on the Devonian of Turkey and adjacent areas. The highly successful meeting was held in the historic main building of Istanbul University which is situated in the heart of the city and overlooking a unique panorama of the Golden Horn. There were two fieldtrips offered in conjunction with the meeting. The first (Sept. 28) led a number of the participants to outcrops covering an almost complete and representative fossiliferous section of Ordovician to Lower Carboniferous sediments in the eastern surroundings of Istanbul. The second fieldtrip was devoted to two major sections in the Taurus Mountains of Southern Turkey (Sept. 30 – Oct. 3). It was attended by only few foreign participants and could therefore be combined with intense cooperative fieldwork on the respective sections by Turkish and German colleagues. Following the transfer to Kayseri as the starting point, some sightseeing in the famous historic center of the town was offered. The next two days were devoted to the Degirmentas Section between Degirmentas and Halevik villages in the NNE of the Tufanbeyli District. The more or less continuous section starts with Cambrian sediments including major carbonates and ends in the Carboniferous, in between covering an almost complete Devonian which was studied in some detail. The next day gave an interesting opportunity to experience some historic places of great importance N of Adana. The subject of the last two days of the fieldtrip was the Civikle Section which is covering most of the Devonian including the Devonian/Carboniferous Boundary. The official part of the field trip was followed by extended fieldwork in the framework of a bilateral Turkish-German cooperation project. Summing up, the workshop and accompanying fieldtrips must be regarded as highly successful. They offered a unique chance to get an insight into the Devonian of Turkey which is covering two major palaeogeographic “complexes” in a nearby setting. The Turkish colleagues have to be thanked for organizing and hosting a great workshop. They not only offered a fascinating Devonian, but also a wonderful landscape, culture and hospitality.

An introductory presentation of the new IGCP took place during the gathering of a good number of members belonging to the international 'Subcommission on Devonian Stratigraphy' (SDS) at an SDS meeting held in Rabat (Morocco) from March 1 to 10, 2004.
The meeting was entitled "Devonian neritic-pelagic correlation and events" and organized by Ahmed El Hassani and his crew at the 'Institut Scientifique de l'Université Mohammed V, Agdal' including an extended field trip to Devonian key sections in the Dra Valley (for link see: http://www.israbat.ac.ma/SemPub/SDS2004/2nd_Circular.htm). 24 oral presentations on Devonian matters including e.g., biostratigraphy, palaeontology, eventstratigraphy, and chemostratigryphy were given during the first two days of the meeting in Rabat. Additionally, 20 posters have been presented touching similar topics. 50 participants from various countries attended this part of the meeting. After the technical sessions an extended fieldtrip to the marvellous Devonian geology of the Dra Valley in the Anti Atlas was attended by 30 participants. The trip was guided by two German groups, Thomas Becker and his crew from Muenster University, and the Senckenberg group from Frankfurt (Gerhard Plodowski and collaborators). The main focus of the trip was set on Lower to Middle Devonian siliciclastics, but minor parts of some sections even reached into the Upper Devonian. A very high grade of biostratigraphic resolution could be demonstrated using a number of taxa (e.g., brachiopods, goniatites, conodonts, tentaculitids, trilobites, ostracods). Other taxa, such as corals and crinoids, have been investigated by attending specialists. Aspects of cyclic stratigraphy and detailed sedimentology and facies analyses have been intensely discussed.
Ahmed El Hassani has put together a volume summarizing the abstracts of the oral presentations and posters on 87 pages (entitled: Devonian neritic-pelagic correlation and events). The 10 contributions to the sections of the fieldtrip (+ intruductionary remarks and an overview article) that had been prepared as a pre-print guidebook for the trip are right now in press to be published as a separate volume [El Hassani, A. (ed.): Devonian neritic-pelagic correlation and events in the Dra Valley. - Documents de l'Institut Scientifique, vol. 19.] within a few months (electronically published on September 21, 2004 - articles available as PDF files via website: www.israbat.ac.ma/PublicationsIS/Doc19_04/sommaireWeb.htm).
During the technical part of the meeting the just accepted IGCP Project 499 was introduced for the first time to the scientists working in the Devonian. Additionally, a brief overview about other new IGCP projects showing some relations to IGCP 499 was also given (e.g., IGCP projects 491, 497, and 503).
6th Baltic Stratigraphic Conference, St. Petersburg (Russia); August 22 – 26, 2005
IGCP 499 has been included this conference that was coordinated by Zivile Zigaite in the framework of IGCP 491 that is focused on mid-Palaeozoic vertebrates (coordinated by Min Zhu and Gavin Young). IGCP 499 was represented by Jurga Lazauskiene who organised a business meeting. There will be more information to come with the next update of the website.
Joint IGCP 499 / SDS Meeting in Siberia, July 25 – August 9, 2005
In the tradition of successful joint meetings and field trips of Devonian IGCP projects and the international Subcommission on Devonian Stratigraphy (SDS) a very successful meeting was held at the Institute of Petroleum Geology, United Institute of Geology and Mineralogy of the Russian Academy of Sciences, Siberian Branch in Novosibirsk. The meeting which included a splendid field trip to the South of Siberia (July 26 – August 6, 2005) and well-organised technical sessions (August 7 – 8, 2005) was run by a great team from Novosibirsk under the guidance of E.A. Yolkin, A.V. Kanygin, N.K. Bakharev, N.G. Izokh and O.T. Obut (and a wonderful team helping to arrange the sessions and the field trip in a perfect way!) was entitled “Devonian Terrestrial and Marine Environments: From Continent to Shelf” (DECONS). About 75 scientists (among them 32 colleagues from foreign countries) presented 35 oral lectures and 44 posters. Business meetings of IGCP 499 and SDS were held on the afternoon of August 8, 2005. The field trip lead the participants to various Devonian outcrops in the Salair, Rudny Altai, and Gorny Altai regions yielding a great variety of rocks in different facies settings (from nearshore/terrestrial to open marine conditions) and from the Lower to the Upper Devonian. Four field camps had to be set up by the perfectly working team. A more detailed report – with more photographs is going to come soon (for first impressions see below). A big “THANK YOU” to our Siberian colleagues for arranging these unforgettable days!

North American Paleontological Convention (NAPC), Halifax, Nova Scotia (Canada), June 19 – 26, 2005
The first North American meeting of IGCP-499 - Devonian Land Sea Interaction: Evolution of Ecosystems and Climate (DEVEC) – met in a symposium titled “Correlation of Devonian Marine and Terrestrial Strata” chaired by D. Jeffrey Over at the June 2005 North American Paleontological Convention in Halifax, Nova Scotia. The oral session consisted of six talks; posters on Devonian topics numbered seven. In addition, several other talks at the meeting were on Devonian floras and faunas. The IGSP-499 session started with an overview of IGCP, IUGS, and the goals of IGCP-499 by Over and others. This also included a review of research projects that deal with refined correlation and nearshore to terrestrial facies under investigation. Bartholomew and Baird followed with descriptions of their research on Middle Devonian strata in New York State, including the sequence stratigraphic position and correlation of the famous buried forest at Gilboa, New York and timing of sea level rise during the major Taghanic flooding and bioevents. Savage described an interesting conodont fauna from the Upper Devonian of Thailand that has implications for paleogeographic reconstructions and dispersal of cosmopolitan faunas. Boyer finished the session with a study of brachiopod faunas in dysoxic strata, looking at community structures and bioturbation relative to oxygen levels. Posters, that were on display for two days, showcased Devonian brachiopod epibionts, fish, and terrestrial vertebrates. The most important aspect of the meeting was the communication between different workers and the development of interdisciplinary projects, especially involving palynologists and macroplant specialists.
In 2004 IGCP has been also presented in other meetings:
11 th International Palynological Congress in Granada (Spain), July 4 - 9, 2004
32 nd International Geological Congress in Firenze (Italy), August 20 - 28, 2004
International Symposium on "Early Palaeogeography and Palaeoclimate” in Erlangen (Germany), September 1 - 3, 2004 (first meeting of IGCP Project 503 "Ordovician Palaeogeography and Palaeoclimate" lead by T. Servais, A. Munnecke, D.A.T. Harper, J. Li, A.W. Owen and P.M. Sheehan)
Annual meeting of the Geological Society of America in Denver (USA), November 7-10, 2004
2004, October, 6: The first IGCP 499 business meeeting
On October 6, 2004 the first business meeting of IGCP 499 was held at the University of Göttingen, Germany, and was attended by about 40 colleagues from 9 countries. The meeting was embedded in the annual meeting of the German Paläontologische Gesellschaft which included a special session on Devonian topics. The business meeting substituted the originally planned meeting in conjunction with the Subcommission of Devonian Stratigraphy (SDS) this fall in Mashad (Iran) which had to be postponed due to organizational problems in Iran. Four of the five leaders of the IGCP 499 were present (only Jurga Lazauskiene was not able to attend) and a substantial number of regional coordinators from different countries contributed to the meeting (see 3.2).
Besides a general overview by the project leaders, colleagues from Belgium (P. Bultynck), China (X. Chen), Germany (Frankfurt group), Iran (M. Yazdi), Poland (G. Racki), Russia (N. Izokh), Spain (J. Valenzuela-Rios), Turkey (N. Yalcin) and the United States (C. Brett) reported about regional plans and initiatives. Presentations and discussions focussed on the activities during the initial phase of the project and how forthcoming activities will be coordinated both, thematically and with respect to future meetings. IGCP 499 meetings will preferably be held in conjunction with the international Subcommission on Devonian Stratigraphy (SDS) as it was the case in the successful initial meeting in Rabat (Morocco) in March 2004.
Press Conference at the Naturmuseum Senckenberg in Frankfurt (Germany), April 28, 2004
The IGCP-National Committee started a press campaing where IGCP 499 has been presented to the general public together with additional information on IGCP projects (poster presentation) in which there are substantial contributions by German colleagues (colleagues acting as leaders and/or co-leaders).
