The Saghez shear zone is part of metamorphic belt of the Sanandaj-Sirjan zone in northwest Iran that uplifted during continental collision between the Afro-Arabian continent and the Iranian microcontinent. The mine is being exploited by open-pits mining, with present reserves estimated at 3.2gr/t gold. The currently favored genetic model is an example of porphyry system, with mineralization being closely to shear bands and emplacement of granit and pegmatitic veins. Rocks from Sagez shear zone consist of metavolca...

Four main mineralized vein Groups within the Sar-Cheshmeh Porphyry system have been identified: I) quartz + molybdenite + anhydrite ± K-feldspar with minor pyrite, chalcopyrite and bornite; II) quartz + chalcopyrite + pyrite ± molybdenite ± Calcite; III) quartz + pyrite + calcite ± chalcopyrite ± anhydrite (gypsum) ± molybdenite; IV) quartz ± calcite ± gypsum ± pyrite ± Dolomite. Early hydrothermal alteration produced a potassic assemblage (orthoclase-biotite) in the central part of the stock, propylitic alteratio...

This paper is devoted to geological and geophysical exploration of Sarband graphite deposits in Markazi province of Iran includes Khanadarreh Bala and Vesmestan deposits. Geological methods include trenching and drilling test pits and exploratory holes, sampling and analyzing with XRD and chemical analysis. This method show that Khanadarreh Bala deposits has purer graphite than Vesmestan and hosted in schistisited rocks and has higher continuity than Vesmestan deposit. Geophysical methods include SP ,mise-a-la-mas...

The Correspondence Analysis Method (CAM) is actually a Non-structural method that could be used to define the anomaly from the background. To apply this method, representative samples of a large area are necessary but knowing the exact location of each sample is not necessary. Base on this method, the litho-geochemical data would be mathematically process to extract the valuable factors needed to plot a two by two diagram. This method has been applied on available data in Enjerd skarn deposit. Five factors have be...
