عنوان مقاله [English]
Structural systems related to iron ore mineralization in the Sangan mining region, northeastern Iran, have a direct relationship with the geometry of deformations. Fractures and faults, linear and planar structures and the influence of igneous bodies as the source of the fluids have the final effect of magmatism on mineralization. The purpose of this study was to investigate and identify the tectonic structures in C-North ore deposit, including a regional structural model with a structural model of ore deposit, and deposit formation model. Due to the location of the Sangan mining area at the end of one of the large-scale branching terminals of the Dorouneh fault, Sangan region is considered as part of the tectonic escape, and many structural functions in the area can be found in the Sangan ore deposits is due to the activity of this phenomenon. By investigating the existing faults in the area and performing a spatial density analysis for each fault series, a fault density map is generated which indicates the three fault systems in the C-North ore deposit. Based on intrusive body studies, the schematic diagram showing the probable accretion style, mechanism of outward building and exsolution of magmatic fluids during the emplacement of magma was presented along with the C-North ore deposit formation model. The results of studying of skarns and C-North ore deposits have great applied scientific significance and can be used for the study of skarn deposits.
