Abstract:

Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the Kahang deposit have an extended range and exhibit a concentric zoning pattern including potassic, phyllic, argillic and propylitic from the center to the margin. The aim of this study was to identify geochemical particulars by geochemical applications in 184 rock samples in these potassic, phyllic and argillic alteration zones. The results of this study show that there are high values of K, Mg and Cu in the potassic zone (located in the central part), main Mo anomalous parts and high Cu values can be found in the phyllic zone (eastern part), and high values of Au, Ti and Al are concentrated in the argillic zone (western part) . Overall, the Kahang deposit hosts Cu, Mo and Au mineralization in these three zones

Resources classification using fractal modelling in Eastern Kahang Cu-Mo porphyry deposit, Central Iran

Resources/reserves classification is crucial for block model creation utilised in mine planning and feasibility study. Selection of estimation methods is an essential part of mineral exploration and mining activities. In other word, resources classification is an issue for mining companies, investors, financial institutions and authorities, but it remains subject to some confusion. The aim of t...

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 ...

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...
