Statistical analyses of data on stream sediments, panned heavy-mineral concentrates, rocks, and waters of the Pusch Ridge Wilderness Area, Arizona
The U.S. Geological Survey and the U.S. Bureau of Mines have conducted a mineral-resource assessment of the Pusch Ridge Wilderness Area, in Pima County near Tucson Arizona. The study consisted of coordinated geological, geochemical, and mineral resource studies with the objective of evaluating the potential for mineral deposits in the 200 km area. The geochemical survey consisted of the collection of stream-sediment samples, stream-sediment samples taken for panning to produce heavy-mineral concentrates, and rock and water samples. The samples were analyzed by both wet chemical and semiquantita-tive emission spectrographic techniques. The sampling procedures, and methods of sample preparation and analysis were reported by Hinkle and others (1981).
