MX Siting Investigation, Gravity Survey - Big Sand Springs Valley, Nevada

摘要

The gravity data for Big Sand Springs Valley shows steeply dipping faults forming a deep graben south and east of Squaw Hills. This graben appears to end near Portuguese Mountain. The eastern range-bounding fault, north of Portuguese Mountain, shows progressively less gravity effect as the valley shoals northward. The extreme south end of the valley is partially obscured by young volcanic flows, but the gravity gives some indication of a deepening beneath the flows. (Author)
