Whole Rock Geochemical Data For Paleozoic Sedimentary Rocks of the western Brooks Brooks Range, Alaska

This report presents geochemical analyses for 210 unaltered and
unmineralized rock samples of Paleozoic age in the western Brooks
Range of northern Alaska. These data form the basis for a study
by Slack et al. (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. A related
geochemical database on altered and mineralized rocks in the Red
Dog Zn-Pb-Ag district is available in Slack and others (2004b).
