Distribution of copper, lead, zinc, mercury, and arsenic in the surface sediments off the coast of northwestern Alaska

Increasing interest in potentially harmful substances utilized and discarded by man has raised question about the normal distribution of chemical elements in the natural environment.  This interest prompted a baseline study of a pristine region off the northern coast of Alaska.  Information was gathered on currents, water clarity, nutrients, temperature and salinity, zooplakton, benthic communitie

Geochemical, aeromagnetic, and generalized geologic maps showing distribution and abundance of antimony and tungsten, Golconda and Iron Point quadrangles, Humboldt County, Nevada

Detailed geologic and geochemical studies of the four 7 1/2-minute quadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun during the 1969 summer field season. The objectives of the project are to map the geology of this structurally complex area at 1:24,000 scale and to determine the regional distribution and abundance of metals in rocks of the area
