Description of new stratigraphic units related to the vast oil-shale deposits of northwestern Colorado.

Definition and description of a useful stratigraphic marker that tongues into the Eocene Uinta Formation.

Definition and description of a conspicuous and useful stratigraphic marker that tongues into the lower part of the Unita Formation.

This volume presents a suite of detailed stratigraphic and sedimentologic investigations of the Eocene Green River Formation of Wyoming, Colorado and Utah, one of the world’s foremost terrestrial archives of lacustrine and alluvial deposition during the warmest portion of the early Cenozoic. Its twelve chapters encompass the rich and varied record of lacustrine stratigraphy, sedimentology, geochronology, geochemistry and paleontology. Chapters 2-9 provide detailed member-scale synthesis of Green River Formation strata within the Greater Green River, Fossil, Piceance Creek and Uinta Basins, while its final two chapters address its enigmatic evaporite deposits and ichnofossils at broad, interbasinal scale.
