Geology of the Great Smoky Mountains National Park. Tennessee and North Carolina

Description: From Preface: "The present account summarizes the results of a long investigation of the rocks of the Great Smoky Mountains (1946-55) by geologists of the staff of the U.S. Geological Survey, in collaboration with those of the Tennessee Division of Geology. The technical details of this investigation have already been set forth at length in professional papers of the U.S. Geological Survey. The present account contains the gist of these findings about the rocks of the mountains, and is accompan… more

Tectonics of Southeastern Arizona

Description: From abstract: The part of Arizona south and east of Tucson is underlain by a wide assortment of deformed rocks, as well as by some major mineralized districts. A synthesis of the tectonic evolution of the region is offered in this report, which is based on older studies of mining districts and on more recent field studies by students and by the U.S. Geological Survey, augmented by field review and selective remapping of many key areas. Through this synthesis the rocks of the region are seen to… more

Quicksilver Deposits of the Opalite District, Malheur County, Oregon and Humboldt County, Nevada

Description: From Introduction: "The Opalite quicksilver district includes two deposits with a considerable past production, one deposit with a small production, and one unproved prospect. These deposits are located along the circumference of a semicircular area that extends from a short distance west of McDermitt, Nev., for about 20 miles along the Oregon-Nevada State boundary. (See fig. 34). The area thus includes parts of Humboldt County, Nev., and Malheur County, Oreg.; almost the entire production has … more

Superposition in the Interpretation of Two-Layer Earth-Resistivity Curves

Description: From abstract: A method is presented for the interpretation of data on electrical resistivity by the superposition of standard reference curves on those obtained from field observations. This method is applicable where bedrock whose average resistivity is essentially uniform is overlain by overburden whose average resistivity is also uniform but markedly distinct.

Geology of Area Between Green and Colorado Rivers, Grand and San Juan Counties, Utah

Description: From Abstract: "The area described in this report comprises about 900 square miles of arid land lying between the Green and Colorado Rivers south of the Denver & Rio Grande Western Railroad and southwest of the Salt Valley anticline. The rocks that crop out or that have been encountered in wells drilled in the are all sedimentary and range in age from Pennsylvania ti Upper Cretaceous. Mesizoic strata are especially well represented."

Tin Deposit at Majuba Hill Pershing County, Nevada

Description: Abstract: The tin and copper deposits at Majuba Hill, Pershing County, Nevada are in a partly brecciated plug of Tertiary rhyolite porphyry, which is altered nearly everywhere to quartz and sericite and in some places is intensely tourmalinized. The tin mineral, cassiterite, appears to be associated with the alteration, for the single concentration of it was formed by replacement of altered breccia. Brecciated and altered rock is, however, only a general guide to potentially tin-bearing ground,… more
