38th Annual GCSSEPM Foundation Perkins-Rosen Research Conference

The Cenomanian-Turonian Stratigraphic Interval Across the Americas: Argentina to Alaska

Dates: 5-7 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.  

Call for Abstracts

We are soliciting contributions for oral and poster presentations from individuals in academic, industry, and governmental organizations with experience in the structural, stratigraphic, oceanographic, climatic, and geochemical characteristics of Cenomanian-Turonian rocks or petroleum products from different locations across this wide-ranging geographic area. These foundational contributions will provide a basis for linking the underlying controls to the rock record, and ultimately the prospectivity of these basins. We intend that these contributions will lead to a more robust understanding of the fundamental mechanisms controlling the global deposition and variability of organic-rich rocks in this exceptional succession, and how this affects our understanding of the carbon cycle. Our goal is that the 38th Annual Perkins-Rosen Conference becomes known as a key milestone in achieving this understanding.

Core Workshop in Houston

Key questions we aim to address

Core Workshop

There will be a core workshop held in conjunction with the 38th Annual GCSSEPM Perkins-Rosen Research Conference on the Cenomanian – Turonian (C-T) stratigraphic interval. The overall goal of the research conference is to understand controls on geologic carbon sequestration using the observed C-T record as a natural laboratory. The aim of the core workshop is to provide participants with hands-on opportunities to examine cores from across the Americas to place the stratigraphic expression of the carbon cycle into the context of sedimentary processes associated with natural carbon sequestration during the C-T interval. Lithofacies and depositional processes seen in core will be linked to the tectono-stratigraphic framework, and climatic, oceanographic, and biochemical processes through core discussions and interactive poster presentations. This will provide an excellent opportunity to unravel how fundamental stratigraphic controls interacted to influence spatial and temporal variability in geologic carbon sequestration in this very unusual time interval in Earth history.

Specific questions to be addressed include but are not limited to: (1) where is the inorganic carbonate stored, and how did it get there; (2) where is the organic carbon stored, and how did it get there; (3) how do the inorganic carbonate and organic carbon each relate to depositional and diagenetic processes, such as production, destruction and dilution, as seen in core; and (4) can we distinguish biogenic carbonate from carbonate cement produced through the mineralization of organic carbonate.

We are soliciting contributions of cores through the C-T interval for the workshop, along with relevant posters to be presented concurrently.  We are looking for a broad geographic range of cores to capture as much spatial variability across the C-T interval as possible. Poster presentations that are tied to core research are highly encouraged.

The core workshop will be held at the Bureau of Economic Geology’s Houston Research Center (HRC) 11611 West Little York Rd, Houston, Texas 77041.
