Environmental-stratigraphic cross sections of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and Paleocene Fort Union Formation, Richland and Roosevelt Counties, Montana
R. M. Flores, C.L. Lepp
1983, Miscellaneous Field Studies Map 1554
This study was conducted to determine the stratigraphic, lithofacies, and deopsitional relationships of the Cretaceous Fox Hills Sandstone and Hell Creek Formation and The Paleocene Fort Union Formation. These relationships, shown in sections A-A', B-B', C-C', and D-D', we established form nearly continuous exposures in the Missouri River valley in...
Preliminary thermal-maturity map of the Cameo and Fairfield or equivalent coal zone in the Piceance Creek Basin, Colorado
Vito F. Nuccio, Ronald C. Johnson
1983, Miscellaneous Field Studies Map 1575
This map was prepared in cooperation with the U.S. Department of Energy's Western Gas Sands Project and was constructed to show the thermal maturity of the Upper Cretaceous Mesaverde Formation (or Group) in the Piceance Creek Basin. The ability of a source rock to generate oil and gas is directly...
Geochemical maps of Bunk Robinson Peak and Whitmire Canyon Roadless Areas, Hidalgo County, New Mexico, and Cochise County, Arizona
Kenneth C. Watts, Jerry R. Hassemer, Gordon W. Day
1983, Miscellaneous Field Studies Map 1425-C
Geochemical sampling of the Bunk Robinson Peak and Whitmire Canyon Roadless Areas was completed in the spring of 1980. The purpose of the geochemical sampling was to determine if certain metals, and "pathfinder" elements in heavy-mineral concentrates and stream sediments are enriched beyond normal black-ground amounts. The enrighment of elemental...
Mineral resource potential map of the Stansbury Roadless Area, Tooele County, Utah
