Sedimentology of the lower part of the upper Triassic Chinle Formation and its relationship to uranium deposits, White Canyon area, southeastern Utah
Russell F. Dubiel
1983, Open-File Report 83-459
Closely spaced measured stratigraphic sections of the lower part of the Late Triassic Chinle Formation in the White Canyon area of southeastern Utah depict a fluvial-deltaic-lacustrine depositional sequence that hosts uranium deposits in basal fluvial sandstones. The basal Shinarump Member consists of predominantly trough-crossbedded, coarse-grained sandstone and minor gray, carbonaceous...

The Emma Bell deposit, Siskiyou Co., California: A possible low-grade source of chromite
B. R. Lipin, Nicholas Wetzel, S. M. Heinrich
1983, Open-File Report 83-816
The Emma Bell chromite deposit in Siskiyou County, California contains over 5 million tons of dunite averaging about 4 percent Cr2O3. Chromite is not evenly disseminated throughout the dunite, however. For the most part the deposit consists of many chromite-rich bands in sharp contact with, and separated by, common dunite...

L.W. Kiteley
1983, Open-File Report 83-820
The uppermost 180 m of the Mancos Shale and overlying 390 m of the Iles Formation of the Mesaverde Group in northwestern Colorado were deposited at the west margin of an epicontinental seaway that spanned North America 66-98 million years ago from the circumboreal seaway on the north to the...

The mineral resource potential of the Wadi Habawnah and Najran quadrangles, sheets 17/44A and 17/44C, Kingdom of Saudi Arabia
Michael D. Fenton
1983, Open-File Report 83-9
The metallic resource potential of the Wadi Habawnah and Najran quadrangles in the southern Precambrian Arabian Shield has been determined primarily by reconnaissance rock geochemistry, limited wadi-sediment and colluvium geochemistry, and gossanous and ferruginous outcrop geochemistry. These surveys were guided by geological information acquired during previous reconnaissance mapping. Locally anomalous...
Analyses of elutriates, native water, and bottom material in selected rivers and estuaries in western Oregon and Washington
Gregory J. Fuhrer, Frank A. Rinella
1983, Open-File Report 82-922
Chemical analyses of elutriates, bottom sediment and water samples for selected metals, nutrients and organic compounds including insecticides and herbicides have been made to provide data to determine short-term water quality conditions associated with dredging operations in rivers and estuaries. Between May and December 1980 data were collected as far...
