Geochemical-geophysical investigations, Fairbanks districtHeiner, L.E.; Beistline, E.H.; Moody, D.W.; Thomas, B.I.; Wallis, J.E.; Loperfido, J.C.; Peterson, R.J.; Wolff, E.N. (University of Alaska Mineral Industry Research Laboratory, 1967)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.
