From text: The Ronda ultramafic complex, a mountainous terrain of peridotites and mafic rocks, rises 1,480 m above the Costa del Sol between Marbella and Estepona in southern Spain. First mapped geologically as part of the Serrania de Ronda by Orueta in 1917, this 300-km2 complex is the world's largest and best-exposed high-temperature peridotite intrusion. Structures and petrologic features within the complex reveal a history of deformation and chemical differentiation related to its upper mantle origins and early movements. The map presented here, which is the result of many seasons of field work by us and other geologists (Buntfuss, 1970; Darot, 1973; Dürr, 1967; Loomis, 1972a; Mollat, 1968), describes both the early-formed, internal features of the complex and its present status as a fault-bounded slab among other tectonic units in the core of the western Betic Cordillera…
