Sedimentary > Carbonate > Limestone (Bed)Mostly massive to thick-bedded, locally cherty; mostly Devonian to Pennsylvanian in age
Incidental
Metamorphic > Schist > Mica-schistBiotite-muscovite schist; protoliths of Cambrian and Late Precambrian age
Metamorphic > Granoblastic > HornfelsIncludes pelitic hornfels and calc-hornfels; protoltiths primarily of Cambrian age
Metamorphic > Metasedimentary > Metaclastic > QuartziteIncludes orthoquartzite and feldspathic quartzite; protoliths of Cambrian and Late Precambrian age
Comments Southern California (San Bernardino Mountains and western Mojave Desert).Consists primarily of limestone, dolomite, calcitic and dolomitic marble, schist, and quartzite. Most rocks are metamorphosed.Includes rocks of Late Proterozoic to Pennsylvanian age.
