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.

The Eska Creek Coal Deposits Matanuska Valley, Alaska

The coal deposits in the vicinity of Eska Creek, a small tributary from the north to the Matanuska River, are a part of the Matanuska coal field. One of the two commercial coal-producing districts in Alaska, this field is in the southcentral part of the Territory, at the head of Cook Inlet. It is 170 miles from Seward, the ocean terminus of the Government-owned and -operated Alaska Railroad, and is served by a branch line of that railroad.

Geology of the Chitina Valley and Adjacent Area, Alaska (open access)

Geology of the Chitina Valley and Adjacent Area, Alaska

From abstract: The Chitina Valley and adjoining area form part of a rugged alpine region in the southeast corner of the main body of Alaska and include a portion of the Chugach Mountains and most of the southern half of the Wrangell Mountains, to the north. The Chitina River is an eastern branch of the Copper River and rises in ice fields and valley glaciers occupying most of the country near the international boundary north of Mount St. Elias. The adjoining area described in this report includes the Hanagita and Bremner River district and the westward continuation of the north side of the Chugach Mountains as far as Valdez Arm and Klutina Lake. In addition, the geology of the upper White River district is described because of its relation to that of the Chitina Valley.

Geologic Appraisal of Dimension-Stone Deposits (open access)

Geologic Appraisal of Dimension-Stone Deposits

From abstract: The construction stone industry comprises two major branches-dimension stone and crushed and broken stone. For purposes of geologic appraisal, deposits of these two categories should be treated separately, because they differ widely in use, mode of development, and exploitation. Deposits of dimension stones are subjected to much greater selectivity with respect to physical properties, uniformity, and modes of occurrence; these demand a much more critical and detailed study of geologic and mineralogic features.

Fluvial Architecture of the Lower Cretaceous Lakota Formation, Southwestern Flank of the Black Hills Uplift, South Dakota

From introduction This report describes large-scale depositional units referred to as architectural elements, interpreted from outcrops of three distinct fluvial sandstone units of the Lakota Formation in the southwestern Black Hills area of Custer and Fall River Counties, South Dakota. These fluvial deposits formed near the end of an episode of continental deposition that began when the Jurassic Sundance sea regressed from the region and ended when the Early Cretaceous Skull Creek sea encroached from the north in Albian time.

Mineral Resources of the Fish Springs Range Wilderness Study Area, Juab County, Utah

Abstract: The Fish Springs Range Wilderness Study Area (UT-050-127) includes most of the Fish Springs Range and is located north of the House Range, about 50 miles northwest of the city of Delta, Utah. A mineral resource study of the 33,840-acre area was completed in 1987 by the U.S. Geological Survey and U.S. Bureau of Mines. The northwestern and southeastern parts of the wilderness study area contain inferred subeconomic resources of high-purity quartzite. No metallic mineral resources were identified in the study area, but more than 17 million pounds of lead, 2.6 million ounces of silver, and minor copper, zinc, and gold have been produced from the Fish Springs mining district, which is immediately outside the northwest boundary of the wilderness study area. The potential for undiscovered deposits of these metals and molybdenum is high near the northern end of the study area, adjacent to the mining district, moderate near the southern end, and low in the remainder of the area. The resource potential for undiscovered deposits of high-purity limestone and dolomite is moderate throughout the study area except where quartzite is present; potential for undiscovered low-temperature geothermal resources and for oil and gas is low throughout the study area.

Eleven areas of mineralized rock in and near the study area were evaluated by the U.S. Bureau of Mines. Four of these areas contain identified resources: (1) an indicated resource of 5,000 short tons of 16.5 ounces silver per short ton, 4.1 percent lead, 4.6 percent zinc, and 0.25 percent copper, at the Willow Springs area, which is almost surrounded by the study area in the northeast corner although it is not part of the study area; (2) an indicated gold resource of 774,000 short tons of 0.4 ounces per short ton and an inferred gold resource of 5.7 million short tons of 0.4 ounces per short ton in the Goshute Canyon area immediately east of the study area; (3) an indicated gold resource of 75,000 short tons of 0.22 ounces per short ton in the Queen of Sheba mine just west of the study area; and (4) an inferred gold resource of 3,800 short tons of 0.26 ounces per short ton in …
