Named for Meeke tin mine. Type section designated as exposures from contact with Oso Canyon Formation, 2.5 mi north of west end of Quail Lake, northeast 1 mi to Kern-Los Angeles Co boundary [La Liebre Ranch 7.5' quad, Los Angeles and Kern Cos, CA]. Exposed discontinuously in southeastern foothills of Tehachapi Mountains from Oso Canyon northeastward 8 mi to Antelope Canyon. Consists of two units of gravel separated by one of clay and clay shale. Is about 1500 ft thick at type. Unconformably overlies Oso Canyon Formation (new); unconformably underlies Pleistocene alluvium. Great angular discordance with underlying upper Miocene formations suggest age is Pliocene or younger, most probably late Pliocene, possibly early Pleistocene(?).
