Hydrothermal alteration mapping using ASTER data in Baogutu porphyry deposit, China
Remote sensing plays an important role in mineral exploration. One of its proven applications is extracting host-rock lithology and alteration zones that are related to porphyry copper deposits. An Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) was used to map the Baogutu porphyry deposit alteration area. A circular alteration mineral zoning pattern was clearly observed ...
متن کاملApplication of mineral chemistry to mineralization and alteration evaluation in Zn-Pb Angouran deposit, Zanjan
Angouran zinc and lead deposit is located about 135 km west of Zanjan city, in the northwest of the Sanandaj-Sirjan structural zone The results of this study indicate that the dolomitic alteration occurred in the carbonate hanging-wall and the presence of ankerite in the schist footwall. The main host of ore deposit is metamorphic carbonate. The Angouran dolomite is secondary and hydrothermal. ...
متن کاملCalculation of Mass Transfer and Element Mobility During the Hydrothermal Alteration in the Sungun PORPHYRY Copper Deposit Iran
The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...
متن کاملGeology and Alteration at the Mount Milligan Gold-copper Porphyry Deposit, Central British Columbia
The Mount Milligan deposit, centred at latitude SS”O8’ north and longitude 124”04’ west, is 100 kilometres westsouthwest of Mackenzie and 160 kilometres northwest of Prince George in central British Columbia. The deposit occurs in gently rolling topography (Plate 2-6-l) 5 kilometres due south of Mount Milligan. Access to the property is by a 93.kilometre logging road that connects with the Hart...
متن کاملApplication of fractal modeling to delineate alteration zones and lithological units in Masjed-Daghi Cu-Au porphyry deposit, NW Iran
In this paper, we aim to present a quantitative modeling for delineating the alteration zones and lithological units in the hypogene zone of Masjed-Daghi Cu-Au porphyry deposit (NW Iran) based on the drill core data. The main goal of this work is to apply Ordinary Kriging (OK) and concentration-volume (C-V) fractal model based on Cu grades in order to separate the different alteration zones and...
