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...

Multivariate analysis is one of the base stage in heavy geochemical prospecting (heavy mineral study). Factor and clustering analysis identify different type of mineralization and the relation between minerals in studied area. But in these methods for each mineral it is necessary to be at least 10 valid samples. Therefore some minerals can’t be analyzed by such methods and we miss some minerals in multivariate analysis and can’t identify the relation between these minerals and others. Jaccard coefficient can be us...

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...

Sungun Porphyry Copper deposit is located 75 kilometers northwest of Ahar and 130 kilometres northwest of Tabriz. In order to model the deposit and estimate its reserve, 31068 input data gained from 152 boreholes were used. Cu grade was selected as the major regional variable on which the present research has focused. All of the available data were changed to 12.5-meter composites so that statistical equalization could be reached. Studies indicated that Cu input data had single - population characteristics. To car...
