Trace Metals Found in the Bedrock of the Ouachita Mountain Region of Arkansas
This Microsoft Excel® spreadsheet contains the trace concentrations (expressed in ppm) of arsenic, chromium, copper, lead, mercury, nickel, and zinc in over 700 samples collected from the Ouachita Mountain drainage basins of the Little Missouri, Caddo, Ouachita, and Saline rivers. Each sample is located by latitude and longitude and includes a stratigraphic and lithic description. This is the sample set that formed the basis of AGC Information Circulars 32 & 35.
