There are scattered exposures of young volcanic rocks in Hamun Lake Area in south western and north western of Zabol in east of Iran. The microscopic evidences and geochemical analysis show that these rocks are olivine basalt and basalt to trachy basalt. The main textures of these rocks are porphyry, microlitic porphyry and vesicular. The main phenocrysts of these rocks are olivine, clinopyroxe...
Chah Torsh intrusive body in S-W of Nadushan is a small part of extensive magmatism of Oligo-Miocene age in Urumieh-Dokhtar magmatic belt. This is the largest intrusive mass of SW of Nadushan complex which are all outcropped as masses cut through Eocene volcanics. The Chah Torsh intrusion consists of two phases with porphyry and granular textures. Geochemical properties of two phases on the bas...
SahebDivan porphyry copper system is located in Alborz-Azarbaijan magmatic zone at northwest Iran. Based on geological surveys, petrographic and geochemical studies, indicated that mineralized stock in this system mainly cosists of granodiorite, diorite and monzonite rocks. These rocks are peraluminous and belong to high-K calc-alkaline and shoshonitic magma series and plotted in the field of I...
Pyrite oxidation, Acid Rock Drainage (ARD) generation, and associated release and transport of toxic metals are a major environmental concern for the mining industry. Estimation of the metal loading in ARD is a major task in developing an appropriate remediation strategy. In this study, an expert system, the Multi-Output Adaptive Neuro-Fuzzy Inference System (MANFIS), was used for estimation of...
The paper reviews and summarizes data on the physicochemical parameters chemical features of mineralizing fluids at porphyry deposits Cu–Mo–Au system. calculated average values ranges in mineral-hosted fluid inclusions are as follows: temperature 90–957 °C, 388 °C; salinity 0.1–88.0 wt % equiv. NaCl, 29.4 NaCl; density 0.38–1.85 g/cm3, 0.93 g/cm3. highest maximum homogenization temperatures wer...
Porphyry copper ore is a vital strategic mineral resource. It often associated with significant hydrothermal alteration, which alters the original mineralogical properties of rock. Extracting alteration information from remote sensing data crucial for porphyry exploration. However, current method extracting ASTER does not consider influence disturbing factors, such as topography, and ignores we...
Abstract: The Urumieh-Dokhtar Magmatic Belt (UDMB) is the host of many Iranian Cu porphyry deposits. Southern part of this belt, in the range of geological Jebal barez, has been less investigated because of the mountainous and rough topography and also some security confrontation. Porphyry deposits are associated with hydrothermal alteration zones can be mapped using remote sensing data such as...
