DescriptionThe Sierrita Mountains are a deeply eroded, ~1,000km2 Basin and Range uplift located 60km south of Tucson, southern Arizona, USA. The Sierritas are dominated by a 35km diameter, 600m-high bajada surface that slopes up and terminates abruptly against a 300m-high, rugged, inselberg core range (~200km2). The bajada is developed on a bedrock surface dominated by two rock types; Paleocene Ruby Star granodiorite (Tgd) in the north, and Cenozoic volcaniclastic conglomerate (Tcv) in the south. Low ranges of rugged hills, composed of Mid-Tertiary lava fields in the south, and strongly mineralized pre-Paleocene rocks in the north protrude through the bajada. The Batamote Hills quadrangle includes the southern half of the core range, and a large area of the southern piedmont. Report and one map sheet, 1:24,000 scale.
