The Kuskokwim mineral belt of Bundtzen and Miller (1997) forms an important metallogenic region in southwestern Alaska that has yielded more than 3.22 million ounces of gold and 400,000 ounces of silver.  Precious-metal and related deposits in this region associated with Late Cretaceous to early Tertiary igneous complexes extend into the Taylor Mountains 1:250,000-scale quadrangle.  The U.S. Geological Survey is in the process of conducting a mineral resource assessment of this region.  This report presents analytical data from 412 rock geochemistry samples collected by the U.S. Geological Survey during the 2005 field season.  All samples were analyzed using the ICP-AES/MS42, ICP-AES10, fire assay, and cold vapor atomic absorption methods described in more detail below.  Analytical values are provided in percent (% or pct: 1 gram per 100 grams), parts per million (ppm: 1 gram per 1,000,000 grams), or parts per billion (ppb: 1 gram per 1,000,000,000 grams) as indicated in the column heading of the data table.  Data are provided for download in Excel (*.xls), comma delimited (*.csv), dBase 4 (*.dbf) and as a point coverage in ArcInfo interchange (*.e00) formats linked below.
