Paperback. Condition: Very Good. First Edition; First Printing. The 1: 24,000-scale geologic map of the Flowery Peak quadrangle is an extension of mapping published recently by the Nevada Bureau of Mines and Geology in the adjacent Virginia City quadrangle. The Flowery Peak quadrangle, southeast of Reno and east of Virginia City, includes part of the Comstock mining district, an important historic source of precious metals. More than 60 lithologic units were mapped in the Flowery Peak quadrangle. Twenty-six units are in the three major mid-Miocene intermediate magmatic groups defined in the Virginia City quadrangle. Extensive Quaternary sedimentary deposits include eighteen units exposed in the Carson River Plains in the southeast part of the Flowery Peak quadrangle. Minor amounts of mid-Miocene sedimentary rocks, early Miocene and Oligocene ash-flow tuffs, late Miocene basalt, and Quaternary rhyolitic rocks are present. Mesozoic metasedimentary and granitic rocks occur as well. Mapping of hydrothermal veins and associated alteration in the Flowery Peak quadrangle extends similar mapping in the Virginia City quadrangle. Twelve new 40Ar/39Ar ages determined for igneous rocks in the Flowery Peak quadrangle, along with chemical and mineralogic data, are reported in text that accompanies the map along with full unit descriptions. This map was prepared as part of the STATEMAP component of the National Cooperative Geologic Mapping Program in cooperation with the U. S. Geological Survey.
