Abstract :
The mine area is located in 65km north of Kashmar(Khorasan-e-Razavi province-East Iran)and it forms a part of northeast of Central Iran zone. This area consists of Paleogene terrigenoussediments containing of shale, marl, sandstone and conglomerate with interlayers of pyroclasticrocks that age of sediments are belonged to Eocene. The faults with East-West trending(parallelwith Doruneh main fault) influenced the region and the formation of this deposit. The mineralogy of deposit is simple and consists of quartz, calcite, stibnite, pyrite, gold, realgar and orpiment. The main type alternations are arjillic, sericitic, pyritization, silicifcation and carbonatization. Field observations, petrography and paragenetic sequences indicate that mineralizationis happened in epithermal vein system.
