This type of oil shale composes about one-half of the oil-shale deposits at the saline depocenter of Eocene Lake Uinta where it is interbedded with the well-known laminated type of oil shale described previously in the literature.Episodic and rapid deposition by lake-bottom currents of large amounts of carbonate-silicate sediments that formed high-grade oil shale is a new concept for the origin of a major part of the Green River oil-shale deposits. In contrast, the laminated oil shale, as previously described, accumulated very slowly as thin varves in a chemically stratified lake under stagnant conditions. This content is PDF only.
