Geology of the Poplar Porphyry Copper - Molybdenum Deposit
The Poplar copper-molybdenum porphyry deposit, 50 kilometres south-southwest of Houston, is centred near 54 degrees 01 minute north and 126 degrees 50 minutes west. The property is accessible from Houston via 80 kilometres of forest access roads along the Morice River, Owen Lake, Tahtsa Reach, and Poplar Lake. The deposit is situated on the northeast shore of Tagetochlain (Poplar) Lake in an ar...
متن کاملdifficulties in the treatment of copper porphyry ores
a high percentage of world copper production is obtained from porphyry copper reserves, these reserves are characterized by: very high tonnage, greater horizontal dimensions than vertical, association with stock like intrusion masses, dispersed minerals in the porphyry mass and in its neighbor rocks, intense sericitization and inplace silicification. the porphyry coppers are concentrated by flo...
متن کاملring structures and copper mineralization in kerman porphyry copper belt, se iran
the role of some ring structures in the distribution of porphyry copper deposits in south kerman porphyry copper belt is discussed. in the study area, ring structures are circular or elliptical shaped features which are partly recognized on satellite images. in this study, landsat multispectral images were used to identify ring structures in the area. the rudimentary identification stages of th...
متن کاملMineralogy, geochemistry and fluid inclusion investigations in the Agh-Darreh copper deposit, Tarom area, NW Iran
Agh-Darreh copper deposit is located in Tarom area, about 25 km north of Abhar city. Main alterations identified in this region include silicic, argillic, and propylitic. Andesite and silica veins host sulfide mineralization. Chalcopyrite and pyrite are the main hypogene minerals accompanied by gold and silver in siliceous veins, with smaller amounts of galena. Malachite, azurite and goethite a...
متن کاملCopper Isotope Constraints on the Genesis of the Keweenaw Peninsula Native Copper District, Michigan, USA
The Keweenaw Peninsula native copper district of Michigan, USA is the largest concentration of native copper in the world. The copper isotopic composition of native copper was measured from stratabound and vein deposits, hosted by multiple rift-filling basalt-dominated stratigraphic horizons over 110 km of strike length. The δ65Cu of the native copper has an overall mean of +0.28‰ and a range o...
