Integraded Geophysical Study of the San Andreas Plate Margin

The goal of this study was to develop a better understanding of structures and plate interactions along the San Andreas continental transform margin using gravity, magnetic and seismic data. Although many geological and geophysical studies have been carried out in the region; most of these have focused on small parts of the plate margin area. Here, an integrated approach is used to investigate the entire transform margin. Because the evolution of continental transforms is reflected in their deep structure, geophysical data have been used to construct 2-D and 3-D models of the crust and uppermost mantle beneath the region. The implications of these models are examined in the context of published geologic evolutionary models for the San Andreas plate margin.
