摘要

Colangüil岩基的南部由二叠纪的Tocota Pluton单元形成，这些单元侵入晚石炭世-二叠纪（Asselian）砂岩。具有新生代安山岩成分和凝灰岩的次火山体、现代山前沉积物层以及冲积层和冰川沉积物也出现了。该地区有一套含金属矿床（Cu-Au-As），偶尔也有铋矿床。这些大多是丝状的。这些岩石在空间上与花岗闪长岩、花岗岩和砂岩有关。它们的发育被解释为属于冈瓦纳旋回。在花岗岩中，矿化作用形成于139ºC至约400°C之间，可能是在托科塔深成岩体固结之后，以及可能与大气降水混合的热液向上循环形成的。在主岩中，矿化发生在200

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
