[Evolution of Sedimentary Basins/Onshore Oil and Gas Investigations--Santa Maria Province: Chapters Y and Z] (open access)

[Evolution of Sedimentary Basins/Onshore Oil and Gas Investigations--Santa Maria Province: Chapters Y and Z]

From abstract: A complex Neogene history characterizes the offshore Santa Maria basin and the northwest margin of the western Transverse Ranges, California. This history includes the transition from subduction to a transtensional and then transpressional plate boundary, including about 900 of clockwise rotation of the western Transverse Ranges. This report uses seismic reflection data to document the geometry of structures that accommodated this deformation and offshore well data to date and correlate the sediments which were affected by the different tectonic episodes.

Report on Progress of Investigations of Mineral Resources of Alaska in 1904 (open access)

Report on Progress of Investigations of Mineral Resources of Alaska in 1904

From letter of transmittal: The report contains fourteen papers, prepared by ten members of the geologic corps, who have been engaged in Alaskan investigations during the last year. In this report an attempt has been made to summarize the economic results of last season's field work. Geologic matter has been entirely excluded, except where it has a direct bearing on the subjects under discussion. While such a report can have no permanent value, other than as a record of mining conditions during the year, it is believed that its prompt publication will help the mining industry of Alaska.

Mineral Industry of Alaska in 1935 (open access)

Mineral Industry of Alaska in 1935

From introduction: The record of the Alaska mineral industry for 1935, here presented, is supplemented by records for earlier years, because in that way certain trends may be recognized which are not only of historical significance but are also useful in suggesting the course that the industry is likely to take in the future. This is a continuing service that has been rendered by the Geological Survey from almost the earliest years of active mining in Alaska, and the present report is the thirty-second of the series.

Spirit Leveling in South Carolina: Part 2. Southern South Carolina, 1896-1938 (open access)

Spirit Leveling in South Carolina: Part 2. Southern South Carolina, 1896-1938

From introduction: This bulletin, which is published in two parts, contains the complete results of all spirit leveling done in South Carolina by the Geological Survey of the United States Department of the Interior, including those heretofore published.' The 34th parallel of latitude, passing through Columbia, serves to divide the State into two sections, each of which is represented by one of the parts of the bulletin. Part 1 deals with the section lying north of the 34th parallel, designated as northern South Carolina, and part 2 deals with the section lying south of that parallel, designated as southern South Carolina. In each part descriptions of the points for which figures of elevation have been determined are listed according to the quadrangles in which the points occur, and the quadrangles are arranged in alphabetic order.

Lode Deposits of the Fairbanks District, Alaska (open access)

Lode Deposits of the Fairbanks District, Alaska

From abstract: To help the mining industry of Alaska and to assist in the development of the mineral resources of the Territory have been the prime motives of the Geological Survey's investigations in Alaska during the past 35 years, in which nearly one half of the Territory has been covered by its reconnaissance and exploratory surveys. It was natural, therefore, that the Alaska Railroad, when it undertook intensive consideration of the problem of finding tonnage that would increase its revenues, should look to the Geological Survey to supply technical information as to the known mineral deposits along its route and to indicate what might be done to stimulate a larger production of minerals and induce further mining developments and prospecting that would utilize its service.

Mineral Resources of the Black Mountains North and Burns Spring Wilderness Study Areas, Mohave County, Arizona (open access)

Mineral Resources of the Black Mountains North and Burns Spring Wilderness Study Areas, Mohave County, Arizona

From abstract: At the request of the U.S. Bureau of Land Management, approximately 19,300 acres of the Black Mountains North Wilderness Study Area (AZ-020-009) and 23,310 acres of the Burns Spring Wilderness Study Area (AZ-020-010) were evaluated for mineral resources and mineral resource potential. In this report, the area studied is referred to, collectively or individually, as the 'wilderness study area' or simply 'the study area'; any reference to the Black Mountains North or Burns Spring Wilderness Study Areas refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management. The study area is located in western Arizona, about 30 mi northwest of Kingman. There are no identified resources in the study area.

Geologic Structure and Occurrence of Gas in Part of Southwestern New York: Part 1. Structure and Gas Possibilities of the Oriskany Sandstone in Steuben, Yates, and Parts of the Adjacent Counties (open access)

Geologic Structure and Occurrence of Gas in Part of Southwestern New York: Part 1. Structure and Gas Possibilities of the Oriskany Sandstone in Steuben, Yates, and Parts of the Adjacent Counties

From introduction: Since the discovery of the Wayne-Dundee gas field in 1930 and the more recent discovery of large quantities of gas in the Oriskany sandstone about 2 miles north of the village of Greenwood the search for similar favorable structural features has been greatly stimulated in the Finger Lakes region and southwestward to the Pennsylvania line. To aid those interested in the area to gain a clearer understanding of the regional structure and its relation to the subsurface structure, parties in charge of the senior author were assigned during the field seasons of 1934 and 1935 to make a geologic study of Steuben County and parts of the adjacent counties.

From introduction: The Red Bluff Bay area was examined briefly for the Geological Survey by John C. Reed and others in 1939. During the summer of 1941 the writers, with R. E. L. Rutledge, mapped this area on a scale of 1:12,000, and examined the serpentine masses in the interior during the course of reconnaissance trips into the surrounding region.

Geology of the Coastal Plain of Georgia

From preface: The manuscript of this report, which is the culmination of field and office studies carried on intermittently s' ice 1914, partly in cooperation with the Geological Survey of Georgia, was completed early in 1938. It was prepared with the expectation that it would form part of a more comprehensive report on the geology of Georgia by several authors, which was intended to accompany a geologic map of the entire State on a scale of 1: 500,000. However, this map without the text was published in 1939 by the Georgia Division of Mines, Mining and Geology. Part of this map is reproduced herein as plate 1 without revision.

Geology of the Coastal Plain of South Carolina

From abstract: The Coastal Plain of South Carolina extends from the Atlantic Ocean inland a distance ranging from 120 to 150 miles to the Fall Line, where it adjoins the Piedmont province. It includes an area of more than 20,000 square miles, or nearly two-thirds of the State, whose total area is 30,981 square miles, of which 494 square miles is water. The geographic divisions of the Coastal Plain are the marine coastal terraces, or "low country", which stand less than 270 feet above sea level, and the Aiken Plateau, the High Hills of Santee, the Richland red hills, and the Congaree sand hills.
