..., with major thrust fault zones traversing northwest to southeast over the region. Major coal-bearing strata of the Wind River Basin are contained in the Upper Cretaceous Mesaverde Formation. The area is divided into seven coal fields and regions: Muddy Creek coal field; Pilot Butte coal field; Hudson (Lander...

... Salt Creek field, situated on an anticline with 1,500 feet of structural closure, has long been recognized as an outstanding example of anticlinal oil entrapment. More oil has been produced from this than from any other field in the Rocky Mountain region (although several other fields ultimately...

... thrust system) and that sediment supply was high (as represented by the upper Ephraim Formation). Subsequent deposition of the Peterson Limestone in the foredeep during the latest Neocomian and Aptian, and the development of a regional unconformity elsewhere, indicate a reduction in sediment supply...

... magmatic lull and lacks young zircon grains, such that timing for thrust initiation is not well constrained, ranging from ca. 130 to 120 Ma. Regional variations in stratigraphic thickness and sedimentation rates, combined with flexural modeling, indicate that a foredeep began developing in front...

..., but comparison of the magnetic formline map ( Figure 6 ) with the northeast-trending pattern of lineaments shows that the dominant trend of magnetic gradients in the southern part of the basin parallels the five northeasttrending lineaments in that region (Orpha/Redbird, Casper/Bill, Natrona/Ross, Arminto/Upton...

... are first-cycle detritus and were apparently derived from crystalhne remnants of the Ancestral Rocky Mountains on the south and southwest. The Lakota Conglomerate of the Casper Arch area has been tentatively correlated with the Lakota Sandstone of the Black Hills region ( Waage, 1958 , p. 72; Wilson...

... that is partially controlled by regional faulting and fracturing ( Hinckley et al., 1982a ). The geology of the Thermopolis area, the area's travertine deposits, and the geochemistry of its hot springs have been studied for more than 100 years. That being said, the last published quantitative study...

... the state is divided. Recent deep drilling makes possible a detailed study of the formation over a wide area in the southwest Powder River Basin, a region interesting for its stratigraphy, its structural position, and its oil production. In order to determine the paleogeography and the depositional...

... in 1902, for exposures near a small coal-mining town situated 2 miles north of Kemmerer, Lincoln County, Wyoming, in the same general region as the localities of Fremont, Hayden, and Meek. The formation was defined as a coal-bearing sandstone formation about 2,000 feet thick, overlain by a thick shale...

The contact between the Meeteetse formation and the overlying Lance formation is apparently conformable throughout the region and is difficult to determine because of lithologic similarities...

Several workers have measured sections in the area of this report, generally as a small part of a regional study. A noteworthy exception is MacClintock (1957) who, in making a detailed...

The dearth of fossils from these strata has been hypothesized to reflect harsh environmental conditions that limited habitable zones across this region ( Cavaroc and Flores, 1991 ; Johnson, 1993a...
