Resumen:
Phyllosilicates geochemistry in the Altar porphyry Cu-(Au) deposit, San Juan, Argentina: applications in exploration, geothermometry, and geometallurgy. Biotite, chlorite, muscovite, illite, and kaolinite from the Altar porphyry Cu-(Au) deposit of the Andean Main Cordillera of San Juan Province (Argentina) were constrained using X-ray diffraction, electron microprobe, and infrared spectroscopy analyses, to map compositional variations. Our study demonstrates that variations in phyllosilicate composition have the potential to be used asvectors in ore exploration and to differentiate between barren and fertile intrusions. A detailed analysis of type and proportion of phyllosilicates, aswell as the presence of ore minerals in fine fractions, should be undertaken to optimize metal recoveries during the upcoming benefaction of these ores.
