The magmatic-hydrothermal evolution of the El Teniente porphyry Cu-Mo deposit in Central Andes Chile is reconstructed based on field relationships, scanning electron microscopy cathodoluminescence, petrography, and fluid inclusion analysis by microthermometry laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS). Three major stages mineralization are observed. Following barren hydrothermal stage 1, 2 characterized quartz-anhydrite stockwork veins breccias with chalcopyrite,...
Abstract The Centinela Mining District ( CMD ), Atacama Desert (northern Chile), includes several mid‐late Eocene porphyry Cu deposits that contains supergene mineralization and provides access to a record of gravel host syn‐sedimentary exotic mineralized bodies. By studying these gravels, we reconstruct the unroofing history constrain geomorphological conditions produced mineralization. We present an integrated study based on stratigraphic sedimentological data, lithology clast counts, 40...

Abstract Supergene copper mineralisation (SCM) processes occur during the unroofing of porphyry deposits. However, geomorphological stage which main occurs is still under debate. Here, we present 24 new thermochronological data from Cenozoic intrusives and compare them with evolution supergene Centinela Mining District in Atacama Desert. Our results indicate a two‐step cooling path: rapid Late Eocene exhumation followed by slow denudation. Previously published ages cluster after Upper...
Exotic type deposits include several species of minerals, such as atacamite, chrysocolla, copper pitch, and wad. Among these, pitch wad have considerable concentrations manganese. However, their non-crystalline amorphous structure makes it challenging to recover the elements interest (like Cu or Mn) by conventional hydrometallurgical methods. For this reason, black ores are generally not incorporated into extraction circuits left unprocessed, whether in stock, leach pads, waste. Therefore,...
Abstract. The occurrence of a distinct type multi‐solid, highly‐saline fluid inclusions, hosted in igneous quartz phe‐nocrysts from the Llamo porphyry, Zaldivar porphyry copper deposit northern Chile is documented. Total homoge‐nization multi‐solid inclusions occurs at magmatic temperatures (over 750d̀C), well above typical hydro thermal fluids (less than 600d̀C) usually recorded systems. analysis this using combination non‐destructive microthermometry, Raman and PIXE techniques...
During the Holocene, patagonian glaciers were characterized by geomorphologically registered advances and retreats. This paper presents geomorphological evolution evidences of Holocene glacial within a segment in Central Patagonia Cordillera. area will be used as reference for studying postglacial paleoclimatic southernmost part South America. The study is Rio Blanco basin (45º30’S), located (Aisen Region, Chile). Radiometric dating organic sediments, terminal moraines, provides preliminary...
