Location of Anomalous Concentrations of Metals in Alaskan Placer Concentrate Samples.
For Reference Only At Bureau Libraries :39 pages
This report consists of 39 mylar overlays prepared by the Bureau of Mines Juneau Field Office. Made to fit 1:250,000 topographic maps of Alaska, these overlays show the location of anomalous concentrations of 25 different metals in magnetic and nonmagnetic placer concentrate samples. The samples, collected by the geological survey during 1895-1953, show high concentrations of metals such as copper, lead, zinc, etc. The overlays could serve as a useful tool in detecting the presence of lode deposits upstream from the sample location.
