Neogene deformation associated with the Wheeler fault, Lake Mead, Arizona

Document

The Gregg Basin area of eastern Lake Mead exhibits a relay in the Wheeler fault system and hanging wall structure with complex three-dimensional geometry. I use high-precision GPS and digital photogrammetry techniques to quantitatively map the geometry of a deformed bed in the Miocene Hualapai limestone. The association of the broad syncline with the relay and lowest structural elevation indicates mechanical interaction between the two faults influenced the location of maximum throw on the Lost Basin Range fault, as well as the area of possible maximum sedimentation and consequently the maximum depth of upper fault tip.
