Green River Basin (Entire Geological Time Period)

Green River Basin (Entire Geological Time Period) Agal-coated tree in paludal environment (note rock hammer lying on algal stromatolites that accumulated on tree roots.) Wasatch Formation, western Green River Basin. Contact between oil shale and trona in the Wilkins Peak Member of the Green River Formation. White crystals in oil shale are mainly shortite [NaCa2(CO3)3]. Photo is from trona mine in central Green River Basin. Multiple Images Paleosol from the Wasatch Formation (stratigraphically equivalent to lowermost Laney Member of Green River Formation, southern Green River Basin). Paleosol is part of a large Eocene fan delta complex on the southern edge of Lake Gosiute.

The conglomerate pebbles are mostly chert. The sandstones are friable (soft) and tend to be thin. Photo by Ryan O’Donnell.
