... rhyolite-basalt eruptive centers northward along the fault ( Dickinson and Snyder, 1978 ; Graham and Peabody, 1981 ). Similarly, the eruption of bimodal volcanics of the Contra Costa Group probably marks initial fracturing along the Hayward fault following the precursor uplift responsible for the clastic...

... ( Bandy and Arnal, 1969 ; Graham and Williams, 1985 ). Dickinson and Snyder (1979a) attributed this subsidence to instability of the Mendocino triple junction and extension of the continental margin. This explanation for the subsidence is compatible with the uplift model presented above if extension...

However, paleochannel elevations compiled from a mining report and geological maps demonstrate that while some modern rivers have incised 560 m below their Eocene–early Oligocene riverbeds...

... and Snyder, 1979). Northward migration of the triple junction marks the onset of the transform margin and wrench fault tectonics resulting in local compression, extension, and formation of local sedimentary basins (Blake et al., 1978; Graham et al., 1984). Early extension appears to have been followed...
