Book Description
The 'sedimentary cover' refers to the stratified rocks of youngest Proterozoic and Phanerozoic age that rest upon the largely crystalline basement rocks of the continental interior. This volume presents data and interpretations of the geophysics of the craton and summarizes the craton's tectonic evolution. It also presents the stratigraphy, structural history, and economic geology of specific sedimentary basins (e.g. Appalachian basin) and regions (e.g. Rocky Mountains). It concludes with a discussion of the currently popular theories of cratonal tectonics, & unresolved questions are identified.

Book Description
Fluvial and lacustrine-dominated clastic sedimentary rocks as thick as 1,800 m (6,000 ft) comprise the Paleocene Fort Union Formation and the Eocene Wasatch Formation of the western Powder River Basin in northeastern Wyoming and southeastern Montana. The systematic mineralogy of 45 samples of channel-fill sandstone from this sequence reflects the uplift and erosion of the Bighorn Mountains. Samples were collected to study vertical changes in the mineralogy of lower Tertiary sandstones adjacent to the Bighorn Mountains, lateral variations in the composition of the upper Paleocene Tongue River Member of the Fort Union Formation along the eastern front of the mountains, and variations in the composition of equivalent upper Paleocene sandstones of the central and western parts of the basin. Vertical changes in the mineralogy of a succession of Paleocene and Eocene sandstone units adjacent to the Bighorn Mountains most likely were produced by uplift and sequential erosion of the rocks that formerly overlaid the mountains. Uplift probably began in the middle Paleocene, during deposition of the Lebo Member of the Fort Union Formation, and continued into the Eocene. Differences in the mineralogy of the sandstone units along the western edge of the Powder River Basin that correspond to differences in the rock types now exposed along the crest of the Bighorn Mountains suggest that much of the erosional degradation of the Bighorn Mountains occurred during an early Tertiary tectonic episode. Lateral changes in the suite of unstable detrital grains within the Tongue River Member are compatible with facies and paleotransport studies that indicate a substantial eastward flux of detritus of early Tertiary age from the Bighorn Mountains into the central Powder River Basin.

Book Description
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.
