Origin and Structure of the Poverty Hills, Owens Valley Fault Zone, Owens Valley, California

Abstract (Summary)

Structural field mapping and analyses of the Poverty Hills reveal a complex deformational geometry consistent with that of a transpressional positive-flower-structure uplift. Kinematic indicators show vertical and horizontal translation facilitated by reverse faulting with a strong oblique strike-slip component. The onset of deformation in the Poverty Hills is estimated at ∼1.7 Ma, and the Owens Valley fault is proposed to have stepped westwards in kinematic response to the rapid development of regional transtensional fault patterns. Geometric modeling of uplift points to a constant slip rate of 1.27-1.44 mm/yr since ∼1.7 Ma on the northern Owens Valley fault. These kinematic, geometric, and temporal relations are utilized to better constrain slip partitioning and distribution across the major fault systems in the region and to characterize the spatial and temporal evolution of the Owens Valley basin, the Owens Valley fault, and the Eastern California Shear Zone in this region.
