Dawsonite and Nahcolite Analyses of Green River Formation Oil-shale Sections, Piceance Creek Basin, Colorado.
Analytical results for nahcolite, dawsonite, total extractable alumina, and oil yield are presented for samples representing Green River Formation oil shales in the saline section of two cores from Colorado's Piceance Creek Basin. Analyses are also reported for samples extending the analyzed section of Colorado Corehole No. 3 Beyond that reported previously. These data permit evaluation of the deposit for possible production of three coproducts--shale oil, alumina, and sodium carbonates--from the saline section of the formation at these sampled points.
