Reverse Osmosis contributing to metal zoning in porphyry type deposits: a case study
(Elsevier Science, 2015-05)
Representing the main source of copper in the world, porphyry copper deposits have been widely studied. Different models have tried to explain the observed metal zoning, but they did not completely explain it. A Permian ...

(Sociedad Geológica del PerúPE, 2014-10)
La presentación desarrolla los siguientes puntos: -Relevance of copper mining in Peru. Peruvian main copper belts and deposits. -Geological models of the main porphyry belts in Peru. -Facts and challenges.
Stochastic rock type modeling in a porphyry copper deposit and its application to copper grade evaluation
(Elsevier, 2015)
An accurate definition of geological domains that differentiate the types of mineralogy, alteration and lithology is a critical step in mineral resources and ore reserves evaluation. Deterministic models define just one ...
Risk quantification with combined use of lithological and grade simulations: Application to a porphyry copper deposit
(Elsevier Science BV., 2016)
The uncertainty in the recoverable tonnages and grades in a mineral deposit is a key factor in the decision-making process of a mining project. Currently, the most prevalent approach to model the uncertainty in the spatial ...
Pliocene lahar deposits in the Coastal Cordillera of central Chile: Implications for uplift, avalanche deposits, and porphyry copper systems in the Main Andean Cordillera
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-03)
Lahar deposits occur within a shallow marine sedimentary succession of the Pliocene La Cueva Formation in the Coastal Cordillera of central Chile (33 degrees 40'-34 degrees 15'S). Provenance studies of the abundant volcanic ...
The role of the Antofagasta–Calama Lineament in ore deposit deformation in the Andes of northern Chile
(2007)
During the Late Jurassic–Early Oligocene interval,
widespread hydrothermal copper mineralization events
occurred in association with the geological evolution of the
southern segment of the central Andes, giving rise to ...
Fission track thermochronology of Neogene plutons in the Principal Andean Cordillera of central Chile (33-35°S): Implications for tectonic evolution and porphyry Cu-Mo mineralization
(Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2009)
Rapid and major coastal subsidence during the late Miocene in south-central Chile
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-03)
Sedimentological and paleontological studies, including foraminifera, ostracodes, gastropods, and trace fossils, were carried Out on Neogene sedimentary successions and offshore boreholes of south-central Chile (similar ...
The relation between trace element composition of Cu-(Fe) Sulfides and hydrothermal alteration in a porphyry copper deposit: Insights from the Chuquicamata Underground mine, Chile
(MDPI, 2021)
Porphyry Cu-Mo deposits are among the world’s largest source of Cu, Mo, and Re, and are also an important source of other trace elements, such as Au and Ag. Despite the fact that chalcopyrite, bornite, and pyrite are the ...
