Geology of the Chuquicamata Mine: A Progress Report
TL;DR: Chuquicamata, in northern Chile, is the world's greatest copper orebody as discussed by the authors, and is controlled by the West fault system, which was controlled from the initial intrusions (probably at 36-33 Ma) through mineralization (last major hydrothermal event at 31 Ma) to postmineral brecciation and offset, by the west fault system.
Journal ArticleDOI
Easter Volcanic Chain (southeast Pacific): A mantle hot line
Enrico Bonatti,Christopher G. A. Harrison,David E. Fisher,J. Honnorez,J.-G. Schilling,J. J. Stipp,Marcos Zentilli +6 more
TL;DR: In this article, the authors show that a chain of volcanic islands and seamounts extends on the Nazca plate eastward from the Easter and Sala y Gomez islands to the islands of San Felix and San Ambrosio, off the coast of Chile (Easter line), in a latitudinal band about 200 km wide.
Journal Article
Fission track thermochronology of the Domeyko Cordillera, northern Chile; implications for Andean tectonics and porphyry copper metallogenesis
Victor Maksaev,Marcos Zentilli +1 more
TL;DR: Aatite fission track (FT) thermochronology provides both age data and a time-temperature history for rocks since they cooled below a temperature of ca. 125 degrees C (equivalent to a depth of 4 km to 5 km under normal geothermal gradients) on their way to the surface during exhumation, or after a heating event as mentioned in this paper.
Journal ArticleDOI
Geochemistry and origin of volcanic rocks of the Andes (26° 28°S)
TL;DR: The chemical variations across the volcanic belt reflect systematic changes in the composition of the magmas due to a decreasing degree of partial melting with increasing depth, and probably also due to the heterogeneity of the source materials as discussed by the authors.
Journal ArticleDOI
Initial 87Sr/86Sr ratios of plutonic and volcanic rocks of the Central Andes between latitudes 26° and 29° south
Robert H. McNutt,James H. Crocket,Alan H. Clark,Juan C. Caelles,Edward Farrar,Simon J. Haynes,Marcos Zentilli +6 more
TL;DR: In this paper, the authors used K/Ar mineral techniques to date 34 plutonic and volcanic rocks covering the entire age span of magmatic events associated with the Andean orogeny between latitudes 26° and 29° south.
