Arizona, Nevada, and California

Comments on Geologic Parameters

16 Rock Mineralogy:

Detailed mineral constituents of the carbonate aquifers in Nevada were provided in tables by Thomas and others (1996). These minerals include calcite, dolomite, gypsum, halite, albite, kaolinite, and K-feldspar. Minor amounts of chalcedony, analcime, and clinoptilolite are reported. Mineralogy of the shallow basin-fill sediments is primarily a reflection of granitic and metamorphic sources (Pool, 1985).
