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...

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 alterations and mineralization occurrences. Due the clear intrusive relationship between the Sabanalarga Batholith and Barroso Formation, and due the Cauca-Almaguer fault cuts both units without separating them, it is suggested that the Terranes Theory must be reconsidered in this part of the country, because the Cauca-Almaguer fault do not correspond to the boundary between Calima Terrane and the terranes Arquía and Quebradagrande.Los Andes Colombianos son el producto de la interacción de terrenos de diferente afinidad geológica, como la Cordillera Occidental, conformada por bloques de afinidad oceánica acrecionados al límite occidental de terrenos preexistentes de afinidad continental. La zona de estudio está dominada geológicamente por el Batolito de Sabanalarga, el cual presenta al menos dos facies, una gabróica-diorítica y una tonalítica-granodiorítica, que intruyen a la Formación Barroso. Ambas unidades se presentan intensamente afectadas por fallas regionales, dando origen a extensas zonas de milonitas íntimamente relacionadas con mineralizaciones y alteraciones hidrotermales. Dada la clara relación intrusiva entre el Batolito de Sabanalarga y la Formación Barroso, y que la Falla Cauca-Almaguer corta a ambas unidades sin separarlas, se sugiere que la Teoría de Terrenos debe ser replanteada en esta parte del país, pues la falla Cauca-Almaguer no correspondería al límite entre el Terreno Calima y los Terrenos Arquía y Quebradagrande.Universidad Nacional de Colombia Sede Medellin.
