Creator:: Raab, Alexander K.
Abstract:: The intrusion-related Cerro Negro Norte Fe-oxide (Cu-Au) deposit is hosted in andesites and diorites of the early to middle Cretaceous Coastal Cordilleran arc of northern Chile. Tabular and irregularly shaped magnetite orebodies are localized on splays and fractures of the regional NINE striking Atacama Fault Zone. Production from this district...

Abstract:: The El Salvador porphyry copper deposit in the Indio Muerto district of northern Chile has been geologically investigated for more than 60 years and provides one of the best bases for understanding similar environments of ore formation elsewhere in the world. Fourteen new zircon U/Pb isotopic ages obtained via in...

Creator:: Schütfort, Erwin G.
Abstract:: The San Vicente zinc lead deposit is located in the Eastern Andes of Central Peru. The deposit is an epigenetic Mississippi Valley-type deposit based on stratigraphic, geologic, petrographic, and geochemical evidence. The dolomite host rocks of the Pucara Group are of Triassic-Jurassic age. The source of metals are red sandstones...

Creator:: Longo, Anthony A.
Abstract:: The Yanacocha Mining District in northern Perú is considered the largest group of high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...

Creator:: Cohen, Julia F.
Abstract:: The detection of subtle variations in mineral chemistry in zoned hydrothermal alteration associated with the formation of porphyry copper deposits by short-wave infrared spectroscopy and rock chemistry are potentially valuable vectoring tools for mineral exploration. In order to correctly interpret the data collected by these methods, results must be calibrated...
