New evidence of magmatic-fluid–related phyllic alteration: Implications for the genesis of porphyry Cu deposits
The phyllic alteration in a number of circum-Pacific porphyry Cu-Au deposits is related to high-temperature saline magmatic fluids. This contradicts the widely used genetic models wherein phyllic alteration formed as the result of mixing between magmatic and meteoric fluids. At the Endeavour 26 North porphyry deposit in eastern Australia, the transition from early potassic to the main-stage phy...
متن کاملWhy large porphyry Cu deposits like high Sr/Y magmas?
Porphyry systems supply most copper and significant gold to our economy. Recent studies indicate that they are frequently associated with high Sr/Y magmatic rocks, but the meaning of this association remains elusive. Understanding the association between high Sr/Y magmatic rocks and porphyry-type deposits is essential to develop genetic models that can be used for exploration purposes. Here we ...
متن کاملPorphyry Cu-Au Deposits of the Iron Mask Batholith, Southeastern British Columbia
The Iron Mask batholith is lo cated 10 km south west of Kamloops (Fig. 1). It is the source of Cu-Au-Ag pro duced from por phyry de pos its such as Afton, Cres cent, Pothook, Ajax West and Ajax East, as well as struc tur ally con trolled Cu-mag ne tite veins (Iron Mask, Makaoo, Grey Mask). Cur rently, it is the tar get of ex plo ra tion for Cu-Au-Ag-Pd min er al iza tion by DRC Re sources at th...
متن کاملGeostatistical Modeling of Electrical Resistivity Tomography for Imaging Porphyry Cu Mineralization in Takht-e-Gonbad Deposit, Iran
This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...
متن کاملApplication of Mixture Tuned Matched Filtering on ASTER Data for Hydrothermal Alteration Mapping Related to Porphyry Cu Deposits in Jabal-Barez Ranges, Kerman Copper Belt, Iran
The study area is located in Jabal-Barez Ranges, southeastern part of Kerman Copper Belt (KCB), where the porphyry copper mineralization such as Kerver occurs. This article deals with the enhancement of hydrothermal alteration minerals for exploration of porphyry Cu mineralization, and differentiates intense hydrothermal alteration zones from those with low intensity. Shortwave Infrared (SWIR) ...
