Geology and lode gold deposits of the Nuka Bay area, Kenai Peninsula, Alaska
Donald H. Richter
1968, Open-File Report 68-229
Nuka Bay is a deep, T-shaped fiord on the southeast coast of the Kenai Peninsula approximately 60 miles southwest of the port of Seward. Gold-bearing quartz veins were discovered in the area in 1918, and between 1920 and 1940 several small mines were in operation around the North and West...
Redefinition of the terms Kingsport Formation and Mascot Dolomite and subdivisions of the upper part of the Knox Group in eastern Tennessee
Leonard Dorrean Harris
1968, Open-File Report 68-119
Upper part of the Knox Group has previously been divided into three formations; however, because of the lack of regionally recognizable boundaries, there has been a marked inconsistency as to the rocks assigned by different workers to the Longview Dolomite, Kingsport Formation and Mascot Dolomite. Regional stratigraphic studies have pointed...
Subsurface geology of the Silent Canyon caldera, Nevada Test Site, Nevada
Paul P. Orkild, F.M. Byers Jr., D. L. Hoover, K. A. Sargent
1968, Open-File Report 68-206
Deep drilling in the vicinity of Silent Canyon on eastern Pahute Mesa, Nevada, has revealed a Tertiary volcanic section locally thicker than 14,000 feet. The area drilled covers most of the Silent Canyon caldera and some of the surrounding area. The caldera is rudely elliptical in plan and measures 10...
A list of references on lead isotope geochemistry through 1966
Bruce R. Doe
1968, Open-File Report 68-76
This bibliography was constructed to be as complete as possible for terminal papetrs containing new data relative to the geochmical applications of Common lead U-Th-Pb isotopic dating Pb-α Pb210, Pb212, Pb214 No effort was made for completeness of: Annual report, Yearbooks, etc. Review papers although many are included. Abstract and these are omitted....
Application of ultraviolet reflectance and stimulated luminescence to the remote detection of natural materials
William R. Hemphill
1968, Open-File Report 68-126
Carbonate rocks and evaporite deposits commonly exhibit relatively high reflectance in the ultraviolet (<3600A), and some outcrops of these materials are selectively shown on ultraviolet imagery. Other materials which are commonly strongly imaged on ultraviolet imagery and photography include water, snow, concrete, and metallic objects, particularly aluminum.Outdoor tests of an...
Mineral investigations between Khamis Mushayt and Bi'r Idimah, Saudi Arabia
William C. Overstreet, U.S. Geological Survey Saudi Arabian Project
1968, Open-File Report 68-208
Mineral investigations between Khamis Mushayt and Bi'r Idimah in the Asir quadrangle, sheet 1-217 (Brown and Jackson, 1959) began September 24, 1964 and ended November 20. Total distance travelled was 6264 kilometers. Sixteen camps were set, and 483 samples of various geologic materials, principally wadi sands, laterite, and gossan, were...
Preliminary results of a trip October 30-December 21, 1965, to the area between Sha'ya and Jabal Bani Bisqan, Saudi Arabia, together with a synopsis of mineral reconnaissance in the Asir quadrangle
William C. Overstreet
1968, Open-File Report 68-209
The area between Sha'ya and Jabal Bani Bisun in the Asir quadrangle has scant evidence of mineralization except for the single small lode gold mine called Al Lugatah, which was examined by D. F. Shaffner in 1957. No part of the area appears to justify immediate further investigation. However, for...
Platinum deposits of Alaska
John Beaver Mertie Jr.
1968, Open-File Report 68-177
The placer deposits of the Goodnews Bay district in southwestern Alaska have yielded the only significant production of platinum metals in the United States, although small amounts of platinum metals have been produced from other deposits in Alaska and elsewhere in the United States. The Goodnews Bay deposits were described...
