Johnson, R.C., Birdwell, J.E., Mercier, T.J., and Brownfield, M.E., 2016, Mineral Occurrence data for the Eocene Green River Formation in the Piceance and Uinta Basins: U.S. Geological Survey data release,


This legacy database lists occurrences of minerals identified in the Green River Formation in the Uinta and Piceance Basins, Utah and Colorado using X-ray diffraction (XRD). The database was compiled from data collected by the U.S. Geological Survey (USGS) and former U.S. Bureau of Mines (USBM). The database includes 1200 samples from 14 cores in the Uinta Basin and 9443 samples from 30 cores in the Piceance Basin; within that dataset over 40 mineral phases are represented between the two basins. Quartz, dolomite, and feldspars are the most common minerals. For nearly a century, these two agencies conducted extensive research on the oil shale deposits of the Eocene Green River Formation, Utah, Colorado, and Wyoming. Beginning in the [...]

These data were digitized for the following purposes: (1) to preserve legacy data on two important resource basins containing oil shale, petroleum (oil and tar sands), aluminum (dawsonite) and sodium bicarbonate (nahcolite) resources; (2) for research into the geochemical variations between and within the two basins to better understand the history of the Green River lacustrine system; (3) to assess co-occurrences of various minerals in order to better understand the geochemistry of the lake and oil shale resource; and (4) to compare with other XRD mineralogy datasets collected on the Piceance and Uinta basin oil shales.
