“…As the movement direction of the Doruneh fault has changed from right-slip to left-slip, the order of significant stress has become reversed, leading to a destructive phase in the region. The younger faults have displaced and cut the mineralization direction [24]. The properties of the structural surveying stations for the Dardvey faults present in Table 2.…”

The system of water flow into the Sangan mineral pit, located in NE Iran, has a direct relationship with the deformations, fractures, and faults. This study aims to investigates, identifies, and analyze the tectonic structures in the Sangan Dardvey deposit, and to determine the regional structural model, deposit structural patterns, and finally provide the deposit's 3D formation model for water entry. The Sangan mining region is located at the end of one of the large-scale branching terminals of the Dorouneh fault, this block is considered a part of a tectonic escape in terms of regional tectonics, and most of the groundwater in the region can be attributed to its activity. The fault density map has been prepared by investigating the faults existing in the deposit area and analyzing the spatial density of faults. The map shows that three faults zones in the Dardvey deposit area are in the E-W, NE-SW, and NW-SE strikes with a dip angle (70°-80°). These fault areas can create paths for the entrance of groundwater into the mineral deposit. Moreover, the structural studies have shown that in the Sangan Dardvey deposits, the fractures play a crucial role in the fault zones, to which the existing anomalies are directly related. The estimation of water entry in the Dardvey deposits has been mainly controlled by tectonic structures.
