      Trace element distribution in a subarctic valley in the Cleary Hill area of the Fairbanks gold district has been studied. Zinc and arsenic have been found excellent pathfinder elements for auriferous deposits. Methods of analysis for copper, lead, zinc, molybdenum, silver and arsenic as well as heavy metals are discussed. The University of Alaska method #2 has been improved, Terrain, slope, and frozen ground have little effect upon the distribution of trace elements associated with the Cleary H i l l vein. A new method for the determination of zinc using dilute acid is proposed. Analysis of geochemical data by trend surface procedures proved effective for localization of anomalies.
    • Investigations of lightweight aggregates in Alaska

      Heiner, L.E.; Loskamp, A.N. (University of Alaska Mineral Industry Research Laboratory, 1966)
      Increased construction costs coupled with the current large demand for aggregate materials prompted an investigation by the Mineral Industry Research Laboratory to find deposits of shale suitable for the manufacture of lightweight aggregate near the cities of Anchorage and Fairbanks.
