Medium-grade metabasites and metapelites from the Cajamarca Complex (Central Cordillera of Colombia) are in fault contact with Jurassic Ibague batholith show a penetrative foliation, locally mylonitic, suggesting intense dynamic–thermal metamorphism. The amphibolites composed calcic amphibole + epidote plagioclase quartz plus rutile titanite apatite carbonate as accessory phases. Chlorite albite appear retrograde replacements. mainly phengite garnet chlorite, haematite Bulk geochemistry...
Abstract We present the first structural geology focused study of a Triassic pluton in Northern Andes, which provides new insights into understanding tectonically complex northwestern corner South America. Based on combination field data (377 stations) and detailed magnetic susceptibility survey, 159 sites, we studied structure Pueblito Pluton (PP), an original suprasubduction mafic cumulate emplaced northern part Arquia Terrane (western margin Central Cordillera Colombia). Even though PP...
The Caicedo Tuffs is a recently mapped Paleocene volcanic arc unit in the northern Andes, which provides insight into magmatism of northwestern South America following its collision with Caribbean-Colombian Oceanic Plateau (CCOP) latest Cretaceous. New regional geological mapping, igneous petrography, whole-rock and pyroxene geochemistry, zircon U-Pb dating are provided for sector eastern flank Western Cordillera Colombia (Antioquia). These data reveal that predominantly composed primary...
The Northern Andes in Colombia developed along an active, convergent margin with a complex subduction-accretion/collision history since Triassic times. Sedimentary basins within, or close to the evolving provide important record for tectonic history. Here we present U-Pb and Hf isotopic data of detrital zircons from Upper Cretaceous Miocene sedimentary strata. In order understand evolution continental during late Paleocene times, two pivotal periods geologic NW Andes, sequences deposited...
