Maps showing trace-element geochemistry of the Sangre de Cristo Wilderness Study Area, south-central Colorado

A trace-element geochemical study of the Sangre de Cristo Wilderness Study Area included the collection of 710 heavy-mineral-concentrate samples, 767 minus-80 mesh stream-sediment samples, and 145 rock samples.  All samples were analyzed for 31 elements by semiquantitative emission-spectrographic methods, and some stream-sediment and rock samples were also analyzed for selected elements by wet che

Mineral occurrence and drill-hole location map of the International Falls 1 degree by 2 degrees Quadrangle, Minnesota and Ontario

A project to assess the mineral potential of the U.S. part of the International Fall 1° x 2° quadrangle was undertaken by the U.S. Geological Survey (USGS) in the early 1984, as part of the Conterminous United States Mineral Assessment Program (CUSMAP).  Because glacial drift covers most of the basement rocks south of the U.S.-Canada border and mineral production in this part of Minnesota has been
