From abstract: Pegmatite occurs widely in Nevada and northwestern Arizona, but little mining has been done for such pegmatite minerals as mica, feldspar, beryl, and lepidolite. Reconnaissance for beryl-bearing pegmatite in Nevada and in part of Mohave County, Ariz., and detailed studies in the Dawley Canyon area, Elko County, Nev., have shown that beryl occurs in at least 11 districts in the region. Muscovite has been prospected or mined in the Ruby and Virgin Mountains, Nev., and in Mohave County, Ariz. Feldspar has been mined in the southern part of the region near Kingman, Ariz., and in Clark County, Nev.

"The purpose of this profile is to summarize the ecological information available for and relevant to stream and riparian habitats of the Great Basin. The Great Basin comprises the northern half of the Basin and Range physiographic province and covers most of Nevada and western Utah and portions of California, Oregon, and Idaho. The entire basin actually consists of numerous subbasins and mountain ranges which present an extremely diverse physical setting" (p. iii).

From introduction: "In this paper are assembled and summarized many subjects relating to the copper industry in North America. Production of mines and districts, history of the industry in North America. Production of mines and districts, history of the industry, geology, of the principal deposits, and mining methods and costs are discussed."

This is a report on the geology and ore deposits of the Goodsprings Quadrangle, Nevada.

From Introduction: "Material for this report was gathered during the last quarter of 1928 and the first quarter of 1929, when the author visited the quick-silver-producing districts of California, Nevada, Texas, Oregon, Washington and Arizona to view the progress made in recent years and gather material for a comprehensive study of the present-day quicksilver industry of the United States."

"The results of analyses of the airborne gamma radiation and total magnetic field survey flown for the region identified as the Death Valley National Topographic Map NJ11-11 is presented in this report"--Abstract.
