Whole Rock Geochemical Data For Paleozoic Sedimentary Rocks of the Western Brooks Brooks Range, Alaska
Listed in NASA Earthdata CMR
This report presents geochemical analyses for 210 unaltered and unmineralized rock samples of Paleozoic age in the western Brooks Range of northern Alaska.
Description
These data form the basis for a study by Slack and others (2004a) on the provenance and depositional history of the Paleozoic strata, and on their metallogenic significance relative to the formation of large stratabound Zn-Pb-Ag deposits in the Red Dog mining district.
Principal rock types that were analyzed include shale, siltstone, sandstone, chert, bedded siliceous rock, and calcareous radiolarite; selected samples of limestone, phosphate, and argillite, and one siderite concretion, were also analyzed. Note that the phosphate samples are from the central Brooks Range, east of the Red Dog district. The geochemical analyses are presented here in Microsoft Excel? and .dbf spreadsheet formats in order to facilitate calculations and plotting of data.
