Abstract

 
The study area is located in sheet 1: 100,000 Ghaenat, 15 km east of Ghaen, South Khorasan province. Interpretation of aerial magnetic data and extraction of magnetic lines along with processing of satellite data indicate the orientation of fractures and major structures in three important directions NS NW-SE, and NE-SW in the region, respectively. The The purpose of this study is to investigate the structural elements in the region such as faults, joints, veins, dikes and to determine the characteristics of faults in the region by emphasizing the mineralization potential of faults and to identify promising areas for copper exploration in the region. The application of a compressive-shear regime creates a tensile space followed by the infiltration of mineralized hydrothermal solutions and extensive alterations. With the development of green schist facies in the area, silica and carbonate are released and the cavities are replaced by malachite (copper oxide), which has led to the formation of malachite nodules within andesitic units. The junction of joints and faults in the study area (faults with northwest-southeast direction and joints with northeast-southwest direction) has high grade mineralization.
