Much of the mineral wealth of Nevada is hosted in pre-Tertiary rocks. These rocks are three times more extensive in the subsurface
at depths of less than 1 km than they are in surface outcrops, (chapter 2). Because of this, a combined portrayal of the exposed
and concealed rocks is crucial to an analysis of Nevada's mineral resources. Plate 4-1 depicts the pre-Tertiary rocks of Nevada
in a way specifically designed to support this analysis. The map shows outcrops (dark colors), as well as the inferred distribution
(pastel colors) of Precambrian, Paleozoic and Mesozoic rocks, divided into 13 assemblages, beneath Tertiary volcanic and sedimentary
rocks, sediments, and alluvium, and Quaternary alluvium and basin fill. The primary source of information for the map is the
Geologic Map of Nevada (Stewart and Carlson, 1978), and most contacts within outcrops are taken from it. In some places, new
contacts have been drawn, based on more recent studies. Nevada Bureau of Mines and Geology OFR-96-2, Plate 4-1, 1: 1,000K
