Development of Reference Stratigraphic Sections

The objective of this research is to develop reference sections for each sub-basin in the Green River Formation (GRF) study area in order to:

1Integrate work on large-scale controls on oil shale formation with lease-scale questions about distribution and characteristics of rich oil shale;
2Provide a stratigraphic framework for comparison of different project areas;
3Provide a means of comparing basin-margin (outcrop) to basin-center (core) deposits, and of comparing Piceance Creek basin (PCB) history with other GRF basins;
4Extend age-determination from the Greater Green River basin of Wyoming to the PCB; and
5Develop sedimentary facies models for predicting quality of oil shale deposits in the GRF and elsewhere in the world.

Additionally, research under this task will study Green River paleospring deposits to determine their influence on evolution of saline lake chemistry and paleoenvironments, and examine evidence for hydrothermal activity and CO2-rich spring inflow; synthesize Piceance Creek Basin and Bridger Basin evaporitic depositional environments; complete definition of sedimentary processes that have occurred in the Green River basins, and initiate comparative work on Uinta basin, in collaboration with the Utah Geological Survey; and complete age determination of tuff sample from R5 zone in the PCB (Hay Gulch section).
