DOWNLOAD EBOOKWhether 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.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKSunrise illuminates Colorado Plateau’s canyon country. In the early morning light, cliffs radiate a rich red glow, and a sculptured panorama of sandstone is revealed in a rich palette of crimson, vermilion, orange, salmon, peach, pink, gold, yellow, and white. Nearby are black, spherical rock marbles (iron concretions) collecting in small depressions, like puddles of ball bearings. These natural spherical balls have been called various names such as iron nodules, iron sandstone balls, or moki marbles. However, we use the name “iron concretion” to describe both the composition (iron oxide that is the dark mineral which cements the sandstone grains) and the formed shape (concretion). What paints the sandstone such rich colors? Why is red a dominant color? Where do the black marbles come from? How did the black marbles form? Is there a relationship between sandstone colors and the marbles? This booklet explores the answers to these questions and poses other questions yet unanswered.

DOWNLOAD EBOOKThe wonderfully grotesque stone sculptures that are Goblin Valley State Park’s main attraction are the consequence of millions of years of geologic history. Within the park are rocks composed of sediments from ancient seas, shorelines, river channels, and playas. With the passage of time these layers of sand, silt, and clay became deeply buried and transformed to rock. Much later, large-scale tectonic forces uplifted the area and prompted erosion to begin to expose the deeply buried layers of rock. Once the rocks were back on the surface, fractures and variations in hardness within the rocks facilitated carving of the goblins by the erosional power of water, wind, and frost. Understanding the rocks and structures of Goblin Valley State Park requires not only an investigation of past and present events that have acted on a small scale within the park, but of past large-scale tectonic events and processes. This booklet is intended to further your understanding of the formation of the goblins, soils, and surrounding scenery or “how they came to be.”

DOWNLOAD EBOOKKane County, with its 4105 square miles, lies along the south-central margin of Utah and is found in the western part of the Colorado Plateaus physiographic province. It is famous for scenic beauty displayed in its colorful rock formations and other geologic features such as faults, folds, arches, monoclines, joints, cross beds, cliffs, lava fields, and canyons. Kane County contains parts of Bryce and Zion National Parks, the Glen Canyon Recreation Area, and it is home to the Coral Pink Sand Dunes and Kodachrome Basin State Parks. The county area has had an interesting geologic history and important fossil finds have added much to our knowledge of world geology. The total value of the mineral production of Kane County, Utah through 1985 is estimated at $21,854,000, of which more than 95 percent is attributed to construction materials, mined or quarried to build and maintain highways. Sand and gravel, crushed stone, coal, gemstones, pumice and volcanic ash, manganese ore, gold, uranium, silver, copper and lead were or have been produced, with the most important current commodities being construction and gem materials. The annual rate of production of these items is erratic, but the value averages a few hundred thousand dollars annually. The production of the construction materials is dependent on the schedules of the Utah Department of Transportation and other road building agencies. Gem materials are mined intermittently to supply the tourist trade. Currently, there are no large, regularly producing mining operations in the county. Other mineral deposits reported in Kane County include titanium and zirconium, gypsum and anhydrite, limestone and dolomite, clay, and vanadium. About 29 tests for petroleum have thus far been drilled without significant success. However, many had interesting shows of oil and gas and the potential for discovery remains high. 192 pages + 10 plates
