The second annual meeting of the International Geoscience Programme Project 653 “Filling the gap between Cambrian Explosion and the GOBE” will be held in Yichang, China from October 8 through 18, 2017.  


Provisional Programme:
  • Oct. 8 (Sunday), 2017: Arrival, registration (ice breaker).
  • Oct. 9 (Monday), 2017: Oral and poster presentations.
  • Oct. 10 (Tuesday), 2017: Oral and poster presentations, workshop.
  • Oct. 11 (Wednesday), 2017: Mid-conference field trip.

Indoor sessions will be held in the Taohualing Hotel, Yichang City, Hubei Province, China.

The mid-conference field trip will visit the Furongian to Middle Ordovician successions, the GSSPs of Dapingian and Hirnantian stages near the Yichang city, and a few historical and scenery sites of Yangtze Gorges.

The post-conference excursion will investigate a number of classic sections of the Guzhangian (Series 3, Cambrian) to Upper Ordovician around the Yangtze Gorges area.

Dayangcha Workshop on the Cambrian-Ordovician boundary, September 20-25, 2017, Changchun, NE China


In the past 16 years, there have been tremendous advances in understanding of the Cambrian-Ordovician boundary on the basis of the study of the GSSP fixed at Green Point, Newfoundland in 2001. New discoveries and knowledge of fossils (conodonts, graptolites, trilobites etc.), radiometric dates and chemo-stratigraphic data have been published at an unprecedented pace. In the meantime, because each research group has been working more or less independently, there have been numerous discrepancies and inconsistencies with regard to important biomarkers of the Cambrian-Ordovician boundary and its relation to chemostratigraphic excursions, and sequence stratigraphic surfaces. This workshop is motivated by the need to resolve these discrepancies and to discuss the feasibility of re-defining a set of criteria for subdivision and correlation of the Cambrian-Ordovician boundary, in China and beyond.
The workshop, supported by NSFC and Ministry of Science and Technology of China (NCSC), will be organized by National Commission on Stratigraphy of China (NCSC), Jilin Provincial Bureau of Land and Resources (JPBLR) and Wuhan Center for Geological Survey (WCGS) (Institute of Geology and Mineral Resources (WIGMR) and hosted by the Research Center of Paleontology and Stratigraphy (RCPS) of Jilin University together with Baishan City Bureau (BCBLR) and Jiangyuan District Bureau of Land and Resources (JDBLR). It will be held from 20-25 September, 2017 at Jilin University, Changchun, NE China. A full two-day in-door meeting will cover all aspects of research on the Cambrian-Ordovician boundary, and the following field excursion of three days will travel to Jiangyuan area of Baishan City to examine the Dayangcha section (potential GSSP for the Cambrian-Ordovician boundary) and another relevant sections nearby, where participants can discuss and identify critical problems that need to be resolved and evaluate possible criteria for subdivision and correlation of the Cambrian-Ordovician boundary. It is hoped that our efforts will better coordinate the development of tools and criteria for study of global Cambrian-Ordovician boundary sections.

IGCP 653 Opening Meeting: Sept. 2016, Durham, UK

The new IGCP project 653, funded for the years 2016-2020, in an international effort to investigate the initiating causes and processes that produced the rapid diversification of marine organisms during the Ordovician Period, known as the ‘Great Ordovician Biodiversification Event’ (GOBE).  The GOBE includes a series of diversifications that completely modified marine food webs and that, for the first time in geological times, established modern marine ecosystems.  Timing of the radiations varied among clades and paleocontinents and may have its roots in the Cambrian.  A diverse set of biotic and abiotic drivers have been proposed to facilitate this diversification, but testing of most of these requires an international effort to improve our data quality and quantity.
