35.3 Pebble-bearing, granular lithic wacke. Blind Beach, Sonoma Coast State Park, California. Fluid-induced, soft sediment deformation modified the fabric of this pebble-bearing sandstone. Black mudrock fragments and brown to gray sandstone clasts comprise the pebbles. The sand grains consist of black lithic clasts, white feldspars, and gray quartz in a gray, mud matrix. Patches of deformed white calcite cement and deformed lenses and layers of dark gray mudrock are prominent in the field of view.
