Antioquia Batholith

The Antioquia Batholith (Spanish: Batolito Antioqueño, Ksta, Kqd, K2ba) is a cluster of plutons located in and named after Antioquia, Colombia. The plutons stretch over an area of about 7,800 square kilometres (3,000 sq mi), and intruded and cooled in Late Cretaceous times. Much of the batholith is weathered into a 40 metres (130 ft) thick saprolite mantle. In some locations this saprolite reaches thicknesses of about 200 metres (660 ft). The development of this weathering is attributed to the humid climate and to stable conditions with limited amounts of erosion. Where the batholith-derived saprolite is eroded, inselbergs, such as El Peñón de Guatapé, crop out. Inselbergs correspond to rock masses of the batholith that resisted weathering and erosion by being less fractured.
