Shapefile
Pink to buff-white, thinly laminated marble units (~ 3 m thick) containing diagnostic hyoliths, interlayered with magenta slate. The basal marble varies from pink to red to orange, whereas the overlying 15-m-thick phyllite varies from maroon and red to green, gray and silver. Intimately associated spatially with OCAcj, such that the two units are grouped together at the presented map scale.

Comments Part of Esmond-Dedham Subterrane (East Bay Area). Printed map states that unit Cpc is mapped with OCcj due to scale, so the digital map unit symbol is Cpc+OCcj.
