This report provides information for use in both short- and long term land-planning decisions, particularly at the county level, and an indication of the present and future economic impact of mineral and energy development. The report discusses eight major commodity groups: (1) oil and gas, (2) coal and coal resin, (3) coal-bed methane, (4) other energy resources (oil-impregnated rock, oil shale, geothermal), (5) uranium and vanadium, (6) metallic minerals, (7) industrial rocks and minerals, and (8) ground-water resources. In general, for each group or commodity within a group the following aspects are discussed: (1) known occurrences and characteristics, (2) past production and trends, (3) current production and exploration activity, and (4) geologic potential. Plates accompany each of the major commodity groups and show the locations of known resources and areas of geologic potential. In addition to the commodity discussions, the report contains a brief summary of land ownership status and concludes with a summary of commodities having the best potential for discovery and development. 161 pages + 14 plates

This report characterizes the relationship of geology to groundwater occurrence and flow, with emphasis on determining the thickness of the valley-fill aquifer and water yielding properties of the fractured rock aquifers. Develops a water budget for the drainage basin and classifies the groundwater quality and identifies the likely sources of nitrate in groundwater.

Whether you are a geologist, history buff, or rockhound, this booklet will be a helpful guide to Utah?s mining districts. The booklet is divided up into three parts: the first part provides general information on what a mining district is, how many mining districts are in Utah, types of mineral deposits found at these districts, and landownership issues. The second part includes individual mining-district discussions containing information on location, production, history, geology, mineralogy, and current/future operations. The third part includes a glossary of geologic terms and other useful resources in the appendices, such as a descriptive list of minerals found in the districts, geologic time scale, and a list of mineral resources of the mining districts.

The San Rafael Swell is an anticline, or a geological uplift, that originally looked like an oval bowl turned upside down. Over time it has been carved into castle-like formations and deep canyons by erosive conditions. This landscape seemed so formidable to early cartographers that it was the last area in the continental United States to be mapped. The San Rafael Swell itself has no permanent human inhabitants, but small towns are scattered along its northern and eastern borders where first American Indians and later cowboys, ranchers, and miners made their homes. The hardy settlers of these towns familiarized themselves with what they called "the Desert" and gradually discovered its treasures and its secrets.

This project compiles basic information on the most important geologic and infrastructural factors that would be considered when planning a new high-calcium limestone quarry such as: (1) data on existing pits and prospects, (2) chemical analyses of high-calcium limestone, (3) the extent and spatial distribution of geologic formations having good potential for high-calcium limestone production, (4) references for geologic maps covering existing pits and prospects, and analytical data points, (5) locations of transportation corridors, and (6) locations of cement and lime plants, electric power plants, coal mines, and metal smelters that are large consumers of high-calcium limestone.

This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.
