the darreh-zar porphyry copper deposit, located in the urumieh – dokhtar magmatic belt, lies about 10 km southeast of sar-cheshmeh porphyry copper deposit. the ore body with hydrothermally altered zones including potassic, chlorite-sericite, sericite, argillic and propylitic all related to the darreh-zar porphyry stock intruded the eocene volcanic rocks. pyrite, chalcopyrite, molybdenite, with ...

maherabad prospect area, which is studied in detail, is the first porphyry cu-au mineralization in the east of iran. based on relation of mineralization with subvolcanic intrusive bodies mostly monzonitic with porphyry texture, extent and types of alteration including potassic, sericitic- potassic, quartz- sericite- carbonate- pyrite, quartz- carbonate- pyrite, silicification- propylitic, propy...

This paper describes the application of a new multi-criteria decision making (MCDM) technique called fuzzy outranking to map prospectivity for porphyry Cu Mo deposits. Various raster-based evidential layers involving geological, geophysical, and geochemical geo-data sets are integrated for mineral prospectivity mapping (MPM). In a case study, 13 layers of the Now Chun deposit located in the Ker...

This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. JKSimMet simulations were used to test various operating and design conditions to improve the comminution process. Modifications to the SABC comminution circuit included ...

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...

This paper offers an analysis of similar and parallel developing projects creating a true philosophy by the disciples followers Origen Plotinus. Two texts permeated eulogy scholarch are analysed: Gregory Wonderworker’s The Address Thanksgiving to Life Plotinus Porphyry. was student Origen, while Porphyry attended his school long enough become familiar with doctrine, teaching methods personality...

Porphyry Cu–Au deposits are the major global source of copper, an essential metal for green transition, and a significant gold. They occur both in thick continental thin oceanic arcs at depths between ∼1 ∼6 km above parental magma chambers situated ∼5–15 depth. Although it is believed that precipitation processes these same arcs, not clear why porphyry two environments display different Cu Au e...

The Pellapahk Cu-Mo and Oleninskoe Au-Ag deposits in the western segment of Russian Arctic Kolmozero–Voronya greenstone belt are considered two parts an Archean (2.83–2.82 Ga) porphyry-epithermal system, probably oldest one defined Fennoscandian Shield. Formation deposit at epithermal stage system is indicated by spatial genetic relationships with sills granite porphyry, geochemical association...

Shortwave infrared (SWIR) technology is characterized by high efficiency and convenience widely used in the mineral exploration of porphyry, epithermal, skarn types. However, studies on SWIR spectral features porphyry tungsten deposits are still lacking. The Dahutang deposit has reached an ultra large scale, type. Based white mica its petrographic, geochemical, Raman features, this paper discus...
