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