Abstract: (564 Views)
The occurrence of copper and gold mineralization in Sultan Anouch area in the southwest of Malayer is a part of Sanandaj-Sirjan zone. The most important rock units in the studied area are schist, limestone and acidic to medium intrusive stocks. The dominant alterations in the area are propylitic, sericite, argillic and hematite, which are locally connected to the formation of skarn. Quartz, epidote, hematite, magnetite, pyrite and malachite minerals are the main ore minerals. The mineralization of gold and copper can be seen as streaks and filling the empty space. In the samples, the highest amount of gold is 0.67 grams per ton and the highest amount of copper is 37200 grams per ton. In the immediate vicinity of the intrusive mass with carbonate rocks, extensive traces of chemical reactions of open system neighborhood transformation have been observed. The intrusive masses are located in the most parts of the volcanic arc granites and at the same time as the impact, so the magmatism of the area is related to the subduction environment.
