Environmental Studies of Mineral Deposits in Alaska

John Gray, Richard Sanzolone, U.S. Geological Survey, U.S. Geological Survey

This collection of articles summarizes environmental geochemical studies of metallic mineral deposits in Alaska, including sulfide, gold, mercury, chromium, and uranium mines and deposits. The studies report metal and acid concentrations in samples collected around such mines and deposits, and evaluate environmental effects of the deposits. An introduction explains geochemical processes, how metals enter environments downstream from mineral deposits, and background geochemical studies. Other articles are: Studies of Mineral Deposits Rich in Heavy Metals; Environmental Geochemistry of Mercury Mines in Southwestern Alaska; Environmental Geochemistry of Alaskan Gold Deposits; Geochemistry of Surface Waters Draining Alaskan Chromite Deposits; and Radioactivity Concerns of Uranium and Thorium Deposits at Bokan Mountain, Southeastern Alaska.
