Hydrothermal alteration and its effects on the magnetic properties of Los Pelambres, a large multistage porphyry copper deposit
(Elsevier Science BV., 2016)
The Los Pelambres porphyry copper deposit is located 190 km north of Santiago, Chile. A paleomagnetic and mineralogical study was conducted at this deposit to determine the effects of hydrothermal alteration on the magnetic ...
Adakite-like signature of Late Miocene intrusions at the Los Pelambres giant porphyry copper deposit in the Andes of central Chile: metallogenic implications
(SPRINGER-VERLAG, 2003-10)
Adakite-like features are recognized in the Late Miocene (similar to10 Ma) porphyritic intrusions of the Los Pelambres giant porphyry copper deposit, central Chile (32degreesS). Located within the southern portion of the ...
High magma oxidation state and bulk crustal shortening: key factors in the genesis of Andean porphyry copper deposits, central Chile (31-34°S)

The Miocene Brahma porphyry Cu-Mo prospect in Central Chilean Andes (35°45′S): Geology, geochronology (U-Pb, Re-Os) and geochemistry
(Elsevier, 2020)
The Brahma prospect is a Neogene porphyry copper deposit located in the Chilean Andes at similar to 35 degrees 45'S, beyond the southerly extension of the previously defined Mio-Pliocene metallogenic belt of Central Chile. ...
Petrology of the Miocene igneous rocks in the Altar region, main Cordillera of San Juan, Argentina: A geodynamic model within the context of the Andean flat-slab segment and metallogenesis
(Pergamon-Elsevier Science Ltd, 2011-07)
The Altar porphyry Cue(AueMo) deposit (31 290 S, 70 280 W) is located in the Andean Main Cordillera of San Juan Province (Argentina), in the southern portion of the flat-slab segment (28e33 S), 25 km north of the world-class ...
Phyllosilicates geochemistry and distribution in the Altar porphyry Cu-(Au) deposit, Andes Cordillera of San Juan, Argentina: Applications in exploration, geothermometry, and geometallurgy
(Elsevier Science, 2016-08)
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 ...
Apatite (U–Th)/He thermochronology and Re–Os ages in the Altar region, Central Andes (31°30′S), Main Cordillera of San Juan, Argentina: implications of rapid exhumation in the porphyry Cu (Au) metal endowment and regional tectonics
(Springer, 2020-10-03)
Altar is a large porphyry Cu (Au) deposit located in the Main Cordillera of Argentina, 20 km to the north of the giant Los Pelambres–El Pachón porphyry copper cluster, at the southern portion of the Pampean flat-slab segment ...
Petrogenesis of Quebrada de la Mina and Altar North porphyries (Cordillera of San Juan, Argentina): Crustal assimilation and metallogenic implications
(Elsevier Science, 2017-09)
We investigate the geology of Altar North (Cu–Au) and Quebrada de la Mina (Au) porphyry deposits located in San Juan Province (Argentina), close to the large Altar porphyry copper deposit (995 Mt, 0.35% Cu, 0.083 g/t Au), ...
