Regional Structural Setting of Yucca Mountain, Southwestern Nevada, and Late Cenozoic Rates of Tectonic Activity in Part of the Southwestern Great Basin, Nevada and California

摘要

Evaluation of the Yucca Mountain area as a potential site for a high-level nuclear waste repository must consider many factors, including geography and hyrology, but both present and future relative tectonic stability of the site area is one of the most important concerns. This report presents a summary of the regional structure and tectonic development, with emphasis on the Tertiary and some preliminary conclusions concerning the tectonic flux in the region surrounding Yucca Mountain. Cahpters are devoted to: structural-physiographic subsections of the southwestern Great Basin; other structural elements of southwestern Nevada; seismotectonics of the southern Great Basin; tectonic setting of Yucca Mountain; and rate of tectonic activity in the Yucca Mountain region.
