Concentration and mineralogical residence of elements in rich oil shales of the Green River Formation, Piceance Creek Basin, Colorado, and the Uinta Basin, Utah; a preliminary report Concentration and mineralogical residence of elements in rich oil shales of the Green River Formation, Piceance Creek Basin, Colorado, and the Uinta Basin, Utah; a preliminary report
Ten core samples of two rich oil-shale beds from the Parachute Creek Member of the Eocene Green River Formation, Piceance Creek basin, Colorado, and Uinta Basin, Utah, were analyzed for 34 major, minor, and trace elements. For 23 of these elements, principal mineralogical residence is established or suggested. Such studies of distribution and mineralogical residence provide important...

Potential shale-oil resources of a stratigraphic sequence above the Mahogany Zone, Green River Formation, Piceance Creek Basin, Colorado Potential shale-oil resources of a stratigraphic sequence above the Mahogany Zone, Green River Formation, Piceance Creek Basin, Colorado
In the southern part of the Piceance Creek basin the upper part of the Green River Formation above the Mahogany zone contains beds of rich oil shale which may be economically recoverable by a surface-mining operation. Four units within this sequence were evaluated for thickness, distribution, oil yield, and potential shale-oil resources. In the area appraised, total estimated resources...

Microprobe analysis of biotites - A method of correlating tuff beds in the Green River Formation, Colorado and Utah Microprobe analysis of biotites - A method of correlating tuff beds in the Green River Formation, Colorado and Utah
Quantitative electron microprobe analyses of biotite grains for iron, magnesium, and titanium from tuff beds in the lacustrine Green River Formation (Eocene) of Colorado and Utah provide a tentative method of identification and a permissive stratigraphic correlation of tuffs. Tuff beds that have been identified and correlated by stratigraphic means were sampled at five localities in...
