چکیده

Abstract: The study area is located 92 Km to the south-east of Torbat-e-Heydariyeh and 12 Km to the north of Shahrak village in Khaf-Dorouneh volcanic-plutonic belt. Rocks in mineralization area are igneous intrusive with porphyric texture and intermediate composition having paleogene relative age and propylitic alteration. Main mineralizations are wide zones of Magnetite-Specularite with Quartz, Calcite, Pyrite, Chalcopyrite, Chlorite, Clay mineral, Goethite, Limonite, Hematite, Malachite and Azurite are minor. Mineralization was formed in fault boundaries and in four stages of them the first one has maximum volume. Analysis of a few samples of mineralization for Au, Cu, Pb and Zn elements using the A.A.S method were done. The amount of copper was 0.2 percent and gold 44 ppb. Microthermometry study of fluid inclusions in Quartz indicated temperature ranges from 160˚C to more than 430˚C and relatively high salinity for mineralization zones. Thermometry study of fluid inclusions in Quartz-Chalcopyrite veins showed Temperatures between 160˚C - 203˚C and relatively high salinity for the solution. Minimum and maximum salinity that obtained were equal to 19 and 31 percent respectively in terms of NaCl. The closest compound system for fluid inclusions was determined H2O-NaCl-CaCl2 triple system. Considering high amount of magnetite and high value of magnetic susceptibility in mineralization, ground magnetic survey was carried out which resulted to the delineation of areas of covered mineralization. Interpretation of magnetic anomalies in profiles, was indicative of the continuation of surface mineralization and increase of magnetite with depth.
