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.

Structural Geology of the Hawthorne and Tonopah Quadrangles, Nevada

Description: From introduction: The object of this paper is to describe the salient features of Jurassic diastrophism in parts of the Tonopah and Hawthorne quadrangles in west-central Nevada. The problem is complicated by the lack of continuity of exposures, earlier folding of the older rocks, metamorphism caused by the later granitic in-trusions, and by superposed Tertiary and later normal faults.

Tertiary Deposits of the Eagle-Circle District, Alaska

Description: From introduction: The present report aims to supply additional information regarding the Tertiary deposits, which are the source of most of the gold placers now being worked in that part of the Eagle-Circle district lying south of the Yukon River. The work was conducted from base camps along the river, but the belt of Tertiary rocks is at places as much as 20 miles from the Yukon, so that it is not easily accessible from the river except in the vicinity of mining camps, where roads or trails have been constructed southward.

Subsurface Geology and Oil and Gas Resources of Osage County, Oklahoma: Part 9. Townships 23 and 24 North Range 7 East

Description: From foreword: This report on the subsurface geology of Osage County, Okla., describes the structural features, the character of the oil- and gas-producing beds, and the localities where additional oil and gas may be found. It embodies a part of the results of a subsurface geologic investigation of the Osage Indian Reservation, which coincides in area with Osage County. The investigation was conducted by a field party of the Geological Survey of the United States Department of the Interior in 1934 to 1937 and involved the study of the records of about 17,000 wells that have been drilled in Osage County.

Geology of the Gerstle River District, Alaska, with a Report on the Black Rapids Glacier

Description: From abstract: The area here described includes most of the north side of the Alaska Range between the Delta and Johnson Rivers, in one direction, and the axis of the Alaska Range and the Tanana River in the other. Besides the Delta River, its principal streams are Jarvis Creek, the Gerstle and Little Gerstle Rivers, and, at the extreme east, the Johnson River, all of which have glacial sources.
