Polymetal and Au skarn deposit determining of Oshvand index Nahavand

Oshvand Poly Metal Skarn is located 15 km East Nahavand. The index is the first metal index sheet 1:100,000 Nahavand which is unique according to the dimensions, carat, and typical of skarn type. Of Geology, Oshvand area is part of Sanandaj – Sirjan zone; Oshvand Skarn is composed of penetrating a granite mass of upper Cretaceous age into Paleozoic limestone. Mineral is exposed in two sections, Exo-skarn and Endo-skarn approximately 300 meters long and 65-91 meters wide and 40 meters height.Store is composed more in the east of skarn,, copper and iron carat was significant in all samples of skarn, and their Average carat is seriate 3439ppm and 105273ppm, So for determine the deposit was used Blocking technique because obtained nearest actual tonnage. After estimating storage can expect potential more than 119 kilograms of gold, 1,717.5 tons zinc 9,574 tonnes of copper and 296,355 tons of iron.
