Geology of the southern part of Sabanalarga Batholith. Implications for terrane theory in the west of Colombia
The Colombian Andes are the product of the interaction of terranes with different geological affinity, such as the Western Cordillera, which is made up of blocks of oceanic affinity, that have been accreted to the western boundary of pre-existing terranes with continental affinity. The study area is geologically dominated by the Sabanalarga Batholith, which has at least two facies, gabro-diorite and tonalitiegranodiorite, that intrude the Barroso Formation. Both units have been affected strongly by regional faults generating large areas of mylonites closely related with hydrothermal alteration... Mehr ...
