For Reference Only At Bureau Libraries :24 pages
In 1978 through 1980, the Bureau of Mines collected a series of 514 panned concentrates from selected granitic regions along a section of the trans-Alaska pipeline corridor, bounded on the south by Livengood and on the north by the Koyukuk River. The methods of sample collection and analytical procedures are described. Sample analyses for tin, as well as for tungsten and eight other common pathfinder elements, are presented. The data indicate both tin and tungsten anomalies in the vicinity of the Northern Ray Mountains to the Sithylemenkat Lake area, near the Fort Hamlin Hills, and west of Caribou Mountain. Only tungsten anomalies occur on Upper Bonanza Creek.
