Identifying Geochemical Anomalies Associated with Cu-Mo Epithermal Mineralization Using PCA and Concentration-Area Fractal Modeling in the Heris Belt, East Azarbaijan (IRAN)

摘要

Due to the diversity of lithology and epigenetic activity, the study area is of great importance for exploration. The area is morphologically composed of Cenozoic and Cretaceous rock formations in a rugged, high northern boundary to the eroded rocky units of Miocene, located in the central and southern ranges. The geological significance of this region is due to the volcanic zone of Urmia-dokhtar in the southwestern part of the region and Sahand tectonomagnetic activities. Intrusive masses are generally diorite, which causes extreme and extensive alteration in Eocene igneous rocks in the study area which is the main source of copper and molybdenum mineralization in the region [1]. On the other hand, in the northwest of this region, there are arsenic deposits in the veins and veins of the realgar and orpiment in the region, which is secondary and extends beyond the boundaries of fractures and faults in this area [2].
