The main goal of the research proposed here is to understand how deformation within continental strike-slip fault systems is partitioned along and across individual fault strands and fault zones over 103 to 105 year timescales. Specifically, this is aimed at better understanding the kinematic and mechanical evolution of the southern San Andreas Fault System (SAFS) in California by: (1) mapping offset landforms through wavelet analysis of high-resolution topography data and geologic fieldwork, (2) dating displaced landforms to obtain precise estimates of fault slip rates at multiple time scales, and (3) using those observations to formulate first-order mechanical models that simulate the behavior and interactions of faults observed in the field. Based on very encouraging results of ongoing similar work on the San Jacinto fault zone, two different dating techniques will be applied to obtain reliable landform ages, terrestrial cosmogenic nuclide exposure age dating and U-series dating of pedogenic carbonate clast-coatings. To fully understand the temporal and spatial partitioning of deformation across the southern SAFS, however, requires detailed geomorphologic and geochronologic study of the Coachella Valley segment of the southern San Andreas fault zone, as proposed here.
