Geochemistry and exploration criteria for epithermal cinnabar and stibnite vein deposits in the Kuskokwim River region, southwestern Alaska
Cinnabar- and stibnite-bearing epithermal vein deposits are found throughout the Kuskokwim River region of southwestern Alaska. A geochemical orientation survey was carried out around several of these epithermal lodes to obtain information for planning regional geochemical surveys and to develop procedures which maximize the anomaly: threshold contrast of the deposits. Stream sediment, heavy-mineral concentrate, stream water, and vegetation samples were collected in drainages surrounding the Red Devil, Cinnabar Creek, White Mountain, Rhyolite, and Mountain Top deposits. Three sediment size fractions; nonmagnetic, paramagnetic and magnetic splits of the concentrate samples; stream waters; and the vegetation samples were analyzed for multi-element suites by a number of different chemical procedures. Nonmagnetic, heavy-mineral concentrates were also examined microscopically to identify their mineralogy.
