38th Annual GCSSEPM Foundation Perkins-Rosen Research Conference

The Cenomanian-Turonian Stratigraphic Interval Across the Americas: Argentina to Alaska (and beyond)

Took place Conference 5-7 December 2022 | Workshop 8-9 December 2022
Location: Houston, Texas

The Cenomanian-Turonian (C-T) is a stratigraphic interval significant for the widespread occurrence of carbon-rich sediments, especially organic-rich mudstones (ORMs), resulting in sequestration of large volumes of organic carbon, and the deposition of major hydrocarbon source rocks and unconventional reservoirs. The coincidence of ORMs with a dramatic carbon isotopic excursion (Oceanic Anoxic Event - OAE-2) and the highest sea-levels of the Phanerozoic, have led to hypotheses that these attributes are produced by complex interactions between the bio-, hydro- and geospheres unique to this period. One common assertion is that high nutrient availability caused high primary productivity in the oceans, resulting in large volumes of organic carbon being fluxed to the sediment-water interface. This carbon input contributed to low oxygen concentrations, which, coupled with reduced water column circulation and reduced coarse clastic inputs, resulted in organic-rich rocks being coincidentally deposited across the globe. But is this the whole story?

The aim of the 38th Annual GCSSEPM Foundation Perkins-Rosen Research Conference is to understand the drivers for the observed C-T record and what this tells us about the carbon cycle and the Earth system. To do this we will (1) examine the C-T sections preserved across the Americas (Argentina to the Arctic); (2) provide a review of the climatic and oceanographic processes that drive the carbon cycle and C-T geological record; (3) provide the latest ideas on the tectonic and paleogeographic context in which these processes operated during the C-T; (4) provide the most recent research on the stratigraphic record of the C-T and how well constrained, or not, this is. The meeting will target successions in diverse depositional basins with varied tectonic histories and different oceanographic settings along this south to north transect. This examination of how the fundamental stratigraphic controls interact to influence facies variability, including organic carbon enrichment, should shed light on this exceptional and important period of the geological record when large volumes of organic carbon were being sequestered, at least locally, from the biosphere into the geosphere. This will provide an excellent opportunity to apply learnings and data from the petroleum industry to better understand the Earth system, especially the carbon cycle.
