Structural geology of the Hawthorne and Tonopah quadrangles, Nevada

The area lies in west-central Nevada near the western border of the Basin and Range province. Paleozoic and Mesozoic rocks the chief subject of this report occur in isolated mountain ranges separated by stretches of Tertiary and Quaternary volcanic rocks, lacustrine deposits and alluvium. The report is concerned principally with the geology of the pre-Tertiary rocks and attempt is made to unravel the complex diastrophisni that occurred in the area during the Jurassic.
