A proposal is under review for a new IGCP project. Information and a new website will follow in the project is accetpted.

Proposed project :

Reading geologic time in Paleozoic sedimentary rocks: the need for an integrated stratigraphy.


Major events punctuated the Paleozoic: ecological crises and diversifications, shifts in ocean chemistry, climatic changes, etc. One of the key-obstacles in understanding these events lays in the difficulty of providing precise estimates of the duration represented by a sequence of Paleozoic sedimentary rocks. This lack of temporal precision severely hampers the evaluation of forcing mechanisms and rates of climatic, ecological or biogeochemical changes in the Paleozoic. It is therefore essential to first improve the Paleozoic timescale to then unravel the history of the Paleozoic Earth system.
Cyclostratigraphy is a powerful chronometer, based on the detection of the Milankovitch cycles in the sedimentary record. Those cycles result from periodic variations in the Earth-Sun system, affecting the distribution of solar energy over the Planet influencing Earth’s climate on time scales between 104 and 106 years. Through the integration of this astronomical time scale with biostratigraphy and radio-isotopic dating, this project intends to document the environmental evolution during the Paleozoic with a focus on the Ordovician to Devonian (485 – 359 million years). It gathers participants (> 200) from all over the world (36 countries) and promotes the participation of young scientists and scientists from developing countries.

Workplan and meetings


  • Special session at European Geophysical Union 2017 meeting (Vienna, Austria, De Vleeschouwer will apply for a session)
  • Special session at the International Meeting in Sedimentology (10-12 October 2017, Toulouse, France, by M. Sinnessael, E. Nardin and A.C. Da Silva will apply for a session)
  • Participation to the 4th International Conodont meeting in Valencia, together with the SDS and ISSS reunion (Valencia, Spain, 25-30 June 2017).



  • Annual project conference to be held in Germany organized by D. De Vleeschouwer, P. Königshof and other leaders
  • Summer school (3 days long, Bremen, Germany) that focuses on the analysis of combined paleoclimatic time series and facies development. The aim of the summer school is to give provide scientists with the tools and skills to answer questions like: “Is my dataset suitable for time-series analysis?”, “Which technique for time-series analysis is most appropriate given the characteristics of my dataset, considering for example hiatuses or strong variations in sedimentary rate?”, “How do I generate and interpret a power spectrum or a wavelet transform, and what are their merits and pitfalls?”. During the summer school, we will familiarize the participants with the free R-package “astrochron”. Why it is essential to understand and interpret facies analysis? This summer school will target early career researchers (PhD students and early postdocs), but will be open to senior scientists with an interest in these questions. Organized by D. De Vleeschouwer, P. Königshof and other leaders.
  • Field workshop (2 to 3 days long, Germany) - 2-3 reference sections, with detailed biostratigraphy. Possible sections include the Effenberg Quarry (mainly cyclic Famennian strata) in the Rhenish Massive. A visit to the world-famous type locality for the Frasnian – Famennian boundary, the Kellwasser section (Harz Mountains) is also planned.



  • Annual Project conference to be held in New York state, U.S.A., by Jeff Over from State University of New York, in conjunction with the Subcommission of Devonian stratigraphy meeting.
  • Field workshop on the Devonian of Pennsylvania and New York state associated with the annual project conference
  • Special session and participation to the IGCP-653 meeting in Novosibirsk, Russia, July 12-19. Main Annual Meeting of IGCP 653. Meeting jointly held with the 13th International Symposium on the Ordovician System (ISOS). Indoor sessions and field excursions to the Lower Paleozoic sections of the Altai Mountains, and northern (Arctic) Siberia.



  • Annual project conference to be held in Brazil (Rio de Janeiro), organized by D. Franco and other colleagues with the other leaders.
  • Field excursions (Paleozoic successions from Itararé Group, Paraná Basin, southeastern Brazil).
  • Special Session at International Geological Congress in India 2020



  • Annual project conference – Closing meeting to be held in China (Lanzhou), organized by Shuang Dai (Lanzhou University), Rongxi Li (Chang’an University), Weiguo Wang (Third Institute of Oceanography State Oceanic Administration, China) and A.C. Da Silva (Liege and Utrecht University)
  • Field workshop on the Ordovician strata in Ordos, China and  on the Cat Ba section in Vietnam associated with the annual project conference
