Mineralizaciones asociadas al Plutón Tocota. Sector Sur del Batolito de Colangüil, Cordillera Frontal, San Juan, Argentina
The southern portion of the Colangüil Batholith is formed by units of the Tocota Pluton, of Permian age, which intrude late Carboniferous-Permian (Asselian) sandstones. Sub-volcanic bodies with andesitic composition and tuffs of Cenozoic age, modern layers of piedmont sediments and both alluvial and glacier deposits also crop out. The region exhibits a set of metalliferous deposits (Cu-Au-As) and occasionally with bismuth. These are mostly filonian type. These are spatially associated with granodiorites, granite and sandstone. Their development is interpreted as belonging to the Gondwanan cycle. Within granitic rocks, mineralizations were formed between 139 ºC and about 400 °C, probably after the consolidation of the Tocota pluton and by the upward circulation of hydrothermal fluids, probably mixed with meteoric waters. In the host rock, mineralization occurred in an interval between 200
