The geology and tectonic history of the northern San Francisco Bay (North Bay) region, California, has not previously been studied in great detail despite the proximity of major population centers to the San Andreas Fault system. Here, the transition from subduction to transform margin tectonics east of the San Andreas Fault took place during the late Neogene and was characterized by northward-younging volcanism and northward-propagating faults.
The papers within this themed issue of Geosphere comprise a series of articles devoted to North Bay tectonics, stratigraphy, and volcanism. They are an outgrowth of concurrent studies in two five-year U.S. Geological Survey projects and a California Geological Survey mapping effort. The papers demonstrate both the multidisciplinary approach and the breadth of geoscience information that is required to understand the tectonic history of the northern San Francisco Bay region. Because of their diversity, these papers will appeal to a wide range of earth scientists interested in these topics and approaches in the North Bay region and in application to analogous areas in other parts of the world.
The most recent papers are at the bottom of the list.
