Shinarump Mesa and some adjacent areas in the Temple Mountain district, Emery County, Utah," by Donald Gc Wyant, January 1953° The investigation upon which this report is based was conducted in 1947» The report has been delayed due to the pressure of other work, but is being transmitted at this time for its possible value in future studies that might be undertaken in the area. As a result of the 1947 work, 950 tons of asphaltite- and carnptite'-bearirig sandstone are estimated to contain from 0.01 to 0.2 per- cent11 uranium^of which"about half ;may contain from 0,1 to 0 0 2 percent, and 90 tons are estimated to contain 0.005 to 08 01 percent uranium. An addi­ tional 1,000 tons of potential ore containing more than 0.01 percent uranium may also be present,, However, inasmuch as the main purpose of the 1947 sampling program was to determine the general uranium content of all of the Shinarump conglomerate at Shinarump Mesa and not to determine re­ serves of minable ore, individual ore bodies were not sampled completely. The Survey plans no additional investigation of the Temple Mountain district at this time.

Wyant ABSTRACT Deposits of uraniferous hydrocarbons are associated with carnotite in the Shinarump conglomerate of Trias sic age at Shinarump Mesa and ad­ jacent areas of the Temple Mountain district in th© San Rafael Swell of Emery County9 Utah. .The irregular ore todies of carnotite-tearing sand­ stone are genetically related to lenticular uraniferous ore "bodies con­ taining disseminated asphaltitie and humic hydrocarbon in permeable sand­ stones and were localized indirectly "by sedimentary controls. .Nearly non-uraniferous "bitumen commonly permeates the sandstones in the Shinarump conglomerate and the underlying Moenkopi formation in the area. The ore deposits at Temple Mountain have teen altered locally "by hydrothermal solutions, and in other deposits throughout the area carnotite has "been transported "by ground and surface water. Uraniferous asphaltite is thought to "be the non-volatile, residue of an original weakly uraniferous crude oil that migrated into the San Rafael anticline; the ore metals concentrated in the asphaltite as the oil was devolatilizad and polymerized. Carnotite is thought to have formed from the asphaltite "by ground water leaching. It is concluded that additional study of the genesis of the asphalt it ic uranium ores in the San Rafael Swell, of the processes "by which the hydrocarbons interact and are modified (such as heat, poly­ merization, and hydrogenation -under the influence of alpha-ray "bombard­ ment), of petroleum source "beds, and of volcanic intrusive rocks of Tertiary age are of fundamental importance in the continuing study of the uranium deposits on the Colorado Plateau. INTRODUCTION The asphaltic ores of uranium and vanadium in the Temple Mountain district, Emery County, Utah have long "been of interest to geologists and, occasionally, to miners. The ore can now "be treated successfully com­ mercially and the importance of the district will probably increase with additional prospecting and the further increase and application of factual geologic data. Prom these data, interpretation may lead to additional discoveries of ore in the San Rafael Swellj and would prob­ ably aid in the "better understanding of the genesis of other uranium deposits elsewhere in the Colorado Plateau.

    Safety Tips Bureau of Land Management To ensure that your stay in the San Rafael area is a safe and enjoyable experience, consider the following safety tips: A dry wash can flash flood in a matter of minutes even if you don't see a cloud in the sky. Never camp or park your vehicle in a stream bed. Recreation Guide Water is essential - at least a gallon per person per day in the summer. If you find free-flowing water, it might not be safe to drink. Carry your own. to the Wear a hat in the summer and remember that extreme temperature changes are possible in all seasons. Anticipate problems. Take extra food, clothing and vehicle repair parts and fluids. San Rafael Area Let someone know where you're going and when you expect to return. If you should break down or become lost, stay with your vehicle - it's a lot more visible to searchers. And speaking of getting lost: the map in this brochure is a general guide. It is a good idea to pick up a large-scale map that shows roads, trails and topography in detail. Bureau of Land Management The San Rafael has historically been a mining area. When you are exploring around San Rafael Resource Area mines, be very careful; old mines and the ground around them can be dangerous. If P.O.
