    Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume The San Juan Basin of northwest New Mexico and south-west Colorado contains huge resources of subbituminous to bituminous coal, nearly half of the U.S. uranium resources, the second largest natural-gas field in the conterminous United States, and several large oil fields. Spread across the states of New Mexico, Arizona, Nevado, California, Utah and Colorado, the Moenkopi is a Lower Triassic formation, red in color and typically sandstone. In Monument Valley, the formation is represented by shale deposits. Parts of the valley have been mined for uranium, which is found in some areas of the Shinarump siltstone.

      Geology of uranium deposits in Triassic rocks of the Colorado Plateau region by Warren Irvin Finch 1 edition - first published in Not in Library. Utah, and the Colorado Plateau are world famous for their Mesozoic and Cenozoic geologic deposits. However, early to middle Paleozoic outcrops on the Colorado Plateau are harder to come by. Most exposures of this age are in Western Utah or along the Uinta Arch.

    The Colorado Plateau is one of the Earth's most strikingly beautiful geological provinces -- and one of the most enigmatic. Millions of years of the planet's evolution are recorded in layer after layer of distinctive geological strata, which are remarkably free from the folding and other distortions that scramble the record elsewhere/5(34).   This new edition of Donald L. Baars's classic The Colorado Plateau incorporates new text, maps, photographs, figures, tables, and bibliography to provide the most up-to-date geology of the red rock and canyon country of the Four Corners of Utah, Colorado, New Mexico, and Arizona. Baars's comprehensive geological summary of the canyonlands is detailed enough to satisfy a geologist Cited by: 4.

Important uranium deposits are widely distributed in the Triassic rocks of the Colorado Plateau region. These deposits, which have been the second most important domestic source of uranium in the United States, have also yielded vanadium, copper, and radium during various periods of mining in the past 50 years.

Atomic Energy Commission. Important uranium deposits are widely distributed in the Trias sic rocks of the Colorado Plateau region, and have been the second mpst productive domestic source of uranium. Vanadium, copper, and radium have been produced from these uranium ores during various periods of mining in the past 50 years.

Host of the deposits in Triassic rocks are Cited by: 4. Uranium deposits formed at nearly all steps of the geological cycle, from high-grade metamorphic conditions (up to °C and 5–7 kbar) for the uranothorianite pyroxenite deposits from the Tranomaro area in the southern part of Madagascar, to plutonic, metasomatic, hydrothermal, basinal diagenetic, metamorphic, and volcanic to sedimentary and superficial environments with the calcretes Cited by: 6.

An isotopic study of sulfide minerals associated with sandstone-type uranium deposits of the Colorado Plateau and Wyoming indicates S 32 /S 34 ratios of these 57 samples varying between to The majority, however, exhibit ratios that are highly enriched in the lighter isotope compared to the ratio of primordial sulfur that is assumed to be similar in ratio to meteoritic troilites Cited by: Geology of uranium deposits.

the rapid increase of uranium mines in the Colorado Plateau playing out at the beginning of the nuclear power era, they became an important source of uranium [6][7. Uranium is found in more than a dozen sedimentary strata on the plateau but the Morrison formation of late Jurassic age and Chinle of Triassic age account for 95% of the produced uranium.

The Morrison was formed from the erosional sediments derived from a highlands called the Elko that existed along what today is the Utah-Nevada border. volumes of sediment onto the Colorado Plateau.

Bentonites, weathered volcanic ash, which occur in Triassic, Jurassic and Cretaceous rocks are evidence of volcanic activity of these distant orogenic belts. The last marine deposits of the Colorado Plateau are Cretaceous in age. This tells us that at this time the plateau was at sea Size: 81KB.

Sedimentary rocks of Jurassic age in the southern part of the San Juan Basin contain the largest uranium deposits in the United States, and offer the promise of additional uranium deposits. Elsewhere in the basin and the adjacent Colorado Plateau, reserves and resources of uranium are known primarily in Triassic, Jurassic, and Cretaceous strata.

The Colorado Palteau Uranium Province (CPUP) is defined by the distribution of uranium deposits, chiefly the sandstone-type, in upper Paleozoic and Mesozoic sedimentary rocks within the Colorado Plateau physiographic province (Granger and others, ).

The uranium province is bordered by widely distributed and mostly minor uranium deposits in Precambrian and Tertiary rocks and by outcrops of. The Jackpile Uranium Mine, which is on the Pueblo of Laguna in northwestern New Mexico was operated from to The small storage coefficients determined from three aquifer tests indicate that the Jackpile sandstone is a confined hydrologic system throughout much of the mine area.

A few notable volcanic deposits are located more centrally within the Colorado Plateau, mainly in the form of volcanic fields.

Colorado mining history is a chronology of precious metal mining (e.g., mining for gold and silver), fuel extraction (e.g., mining for uranium and coal), building material quarrying (iron, gypsum, marble), and rare earth mining (titanium, tellurium).

The Uravan Mineral Belt (UMB) is on the west side of the state, and the Colorado Mineral Belt (COMB) is a large area of the state had gold.The Cameron uranium-mining area is centered around the settlement of Cameron, Arizona, which is 52 miles north of Flagstaff (Figure 1).

This area contains numerous uranium ore deposits in the Upper Triassic Chinle Formation. Cameron is the fourth largest area on the Colorado Plateau that produced uranium from this geologic unit.Abdel-Gawad, A.
