... (~252 Ma) until the end-Smithian (Early Triassic; c. 250.7 Ma) in the Sonoma Foreland Basin show marked thickness variations between its southern (up to c. 250 m thick) and northern (up to c. 550 m thick) parts. This basin formed as a flexural response to the emplacement of the Golconda Allochthon...

..., and is laterally fault bounded. The subprovince is bisected diagonally by a major fault zone from its southwest to its northeast corner. The Sonoma and Orinda basins in the northwestern part of the subprovince are separated by the Carquinez Strait. The Livermore basin, south of the Carquinez Strait, occupies...
