At the center of Bidkhan, there is an area of approximately 10 km2, which is an altered volcanic-intrusive complex. Effort will be made to provide a more accurate picture of the alteration landscape across Bidkhan on the map. The purpose is to clarify how alteration at several points has occurred so as to understand the features of alteration. The altered area is covered by younger events, which have in turn gone through alteration covering another type of alteration on the lower layer. Studies show that there are no traces of either metallic or non-metallic mining activities in the region. The only notable point is the rare remnants of slags spread sporadically across one spot of the region. It is unknown where the small pieces of slag about 10 cm × 10 cm originate from and which mineralization is involved. It seems that due to the expansion of copper mineralization at Bidkhan, the slags are produced from the copper smelting.展开更多

This region includes all the heights and villages that are known by the name of Bidkhan. Chemical nomenclature of igneous rocks is performed with the help of main oxide plots. Based on the analysis results of the samples with minimum alteration, position of these samples was obtained on special diagrams. The achieved data should be compatible with field evidences at a regional scale. There are some limits to the interpretation of the harvested samples on chemical nomenclature diagrams for igneous rocks that should be taken into account. Lithology of Bidkhan region was performed using the main oxides that were obtained from XRF method. 30 sample rocks, which were very fresh and without alteration, were used for drawing diagrams and determining the position of these regional rocks on the chemical nomenclature diagrams for igneous rocks. The results for the analysis of the main oxides of these 30 samples are also presented.展开更多

The findings from various sections indicate that diverse topological events in a zonal and regional time span have resulted in physiochemical (thermodynamic) systems leading to expansive alterations (metamorphism) and mineralization in the central region of Bidkhan area. Alterations such as Propylitic, Silicating, Argillic, Phyllic and even Potassic concentrates at an area of about 10 km2 together with such structures as fissures have created the required and suitable condition for the formation of thermodynamic systems. Such systems are related to mineralization fluids mineralizer that accompanies the sort of activities that are clearly indicative of the existence of an active igneous source all forming a terrene at Bidkhan region which is very similar to mineralization porphyry systems.展开更多
