This report uses log analysis methods to analyze and compare "geologic and hydrologic data obtained from well tests and core studies," focusing specifically on the Edwards aquifer in Texas. It contains maps, tables, and figures.

The following report examines the mineral resources and geologic relations of the pre-Cambrian rocks and the associated iron ores in the Llano-Burnet region, Texas.

Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

Article about Natural Gas Reserves production and Consumption in Dallas, Fort Worth in Texas

A collection of writings on the shorter contributions to general geology.

This document reports the presence of oil and gas in Palo Pinto County, Texas, as studied by the United States Geological Survey in the fall of 1914.

From abstract: This report describes the geology of the Marathon region, in trans-Pecos Texas. The Marathon region lies on the edge of the Mexican Highlands province, where that province merges into the Great Plains on the east. Structurally, the region is a broad dome of Cretaceous rocks, from whose central part the Cretaceous cover has been stripped away, leaving an area of low country in the center, the Marathon Basin. Here strongly folded Palcozoic rocks are exposed. The Monument Spring and Marathon quadrangles, described in detail in this report, extend across the basin area.

From summary: This report details the survey of the potash field of southeastern New Mexico and adjacent parts of Texas. The material described in this report was obtained from drill cores and well cuttings.

From introduction: This report presents the findings of surveys of the extent of the oil fields in the gulf coastal plain.

The following report is a synopsis of readily available information on the mineralogy, thickness and areal extent of soluble salt deposits in the Ochoa series of Permian age in southeastern New Mexico and western Texas. It's part of a more extensive investigation of salt being carried out by the U.S. Geological Survey in connection with its Investigation of Geologic Processes project on behalf of the Division of Research, U.S. Atomic Energy Commission.

From purpose and scope: The purpose of this report is to present preliminary results of the study by the Geological Survey on the following: (1) The existing ground-water conditions in the shallow fresh-water system in the vicinity of the proposed Truscott Brine Lake (figure 1) and (2) the projection of the post-construction effects of the proposed Truscott Brine Lake on the fresh-water aquifer, especially in relation to changes in hydraulic head but also with respect to possible changes in the chemical quality of the ground water.

The following report includes all the results of spirit leveling in Texas, rearranged by quadrangles.

From introduction: The district discussed in this report embraces the entire northern peninsula of Michigan and the parts of northern Wisconsin and northeastern Minnesota that were covered by a re-advance of the Superior lobe of the Labrador ice sheet late in the Wisconsin stage of glaciation.

Abstract: This report is a synthesis of published and unpublished data on the rocks of the Anadarko basin.

Report discussing the stratigraphy of uraniferous rocks discovered near Tordilla Hill in Karnes County, Texas. The report contains sections on the stratigraphy of the area, the structure, uranium minerals, descriptions of individual prospects, and a summary.

From Abstract: "This report deals with an area of 425 square miles in the western part of Texas, immediately south of the New Mexico line. The report describes the geology of the area, that is, the nature of its rocks, tectonics, and surface features, and the evidence that they give as to the evolution of the area through geologic time. Incidental reference is made to the geology of surrounding regions in order to place the area in its environment."

From abstract: This report describes four species of Ostreidae from the Upper Cretaceous of the Gulf region. The zones that the species characterize lie either in the upper part of the Austin chalk or in beds of upper Austin age.

The following report summarizes the locations, resources, and petrophysical data of known bitumen-bearing deposits located primarily in Alabama, California, Kentucky, Texas, and Utah.

A report pertaining to uranium which has been found in two stratigraphic zones in rocks of permian age in northern Texas and south-central Oklahoma.

This article is based on the production of oil in the Caddo oil and gas field on the Gulf Coastal plain.

From introduction: The U.S. Army Corps of Engineers, Fort Worth District, is studying the long-term availability of the existing ground-water supplies at North Fort Hood. In connection with this study, the Corps asked the U.S. Geological Survey to compile the available ground-water data, to collect data on current conditions, and to assess the effects of ground-water development in the vicinity of North Fort Hood. These items are presented in this report.

Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.
