Bituminous-Coal Deposits in the Vicinity of Eska, Matanuska Valley Coal Field, Alaska

Description: Report of investigations issued by the U.S. Bureau of Mines on the estimated recoverable reserves of bituminous coal found in the Matanuska Valley Coal Field. The investigation includes studies of the area, and methods of mining which include diamond and churn drilling. This report includes maps, photographs, and illustrations.

Mineral Industry of Alaska in 1938

Description: From introduction: The presentation of a yearly record of the Alaska mineral industry is a continuing service that has been rendered by the Geological Survey from almost the earliest years of extensive mining in Alaska, and the present report, for 1938, is the thirty-fifth of this series. 2 Such a record, especially when supplemented by the statistics for the preceding years, not only affords an authoritative summary of current 'and past conditions but also indicates trends that are of significance in suggesting the lines along which future developments of the industry are likely to proceed. These reports therefore serve miners, prospectors, and businessmen concerned with Alaska affairs as useful historical records, statements of contemporary conditions, and starting points on which some conjectures concerning future operations may be predicated.

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.

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.

Radioactivity and Mineralogy of Placer Concentrates From the Fortymile District, Alaska

Description: Report discussing the study of radioactivity and mineralogy of 24 placer concentrate samples from the Fortymile district of east-central Alaska. Only two samples showed significant radioactivity due to uraniferous thorianite. Sections include geology, and radiometric and mineralogic studies.

Radioactivity in the "Okpilak" Gneissic Granite Mount Michelson Area, Northeastern Alaska

Description: The following report discusses radioactive results found in 4 samples of gneissic granite of 13 samples collected from the Mount Michelson area of northeastern Alaska. A mineralogic study of all heavy-mineral fractions having more than 0.01 percent equivalent uranium indicates that the radioactive material apparently is confined to biotite, which in one sample contains 1.19 percent uranium.

Reconnaissance for Uranium and Thorium in Alaska, 1954

Description: The following report covers a reconnaissance for uranium and thorium in Alaska during the 1954 field season that consisted principally of a study of the radioactive beach placers east and west of Cape Yakataga, and ground and airborne radiometric traverses of portions of Kodiak Island and adjacent islands.

Reconnaissance for Radioactive Deposits in Southeastern Alaska, 1952

Description: Report discussing an investigation of radioactivity occurrences, mostly caused by thorium in thorite and monazite, in various parts of southeastern Alaska. The geology and structural qualities of these radioactive areas are discussed.

Reconnaissance for Radioactive Deposits in the Buckland-Kiwalik District, Candle Quadrangle, Seward Peninsula, Alaska

Description: Report discussing the U.S. Geological Survey's investigation of radioactive mineral deposits found in the Buckland-Kiwalik district on the Seward Peninsula of Alaska. Uranothorianite, as well as other radioactive minerals, were discovered in the area.

Lead-Alpha Age Determinations of Granitic Rocks from Alaska

Description: Abstract: "Lead-alpha activity age determinations were made on zircon from seven granitic rocks of central and southeastern Alaska. The results of the age determinations indicate two periods of igneous intrusion, one about 95 million years ago, during the Cretaceous period, and another about 53 million years ago, during the early part of the Tertiary. The individual ages determined on zircon from 2 rocks from southeastern Alaska and 1 from east-central Alaska gave results of 90, 100, and 96 million years; those determined on 4 rocks from central Alaska gave results of 47, 56, 58, and 51 million years."
