Abstract :

The region is located in east part of Torbat-e-Jam. It is placed along the east side of Alborz Mountains and close to the suture zone of Iran and Tooran plate, on the Iranian side. The rock units are as follows: shale, conglomerate (Jurassic), marl, limestone, basalt, andesite, trachyandesite, tuff, agglomerate plus rhyodacite and quartz monzonite dikes (paleogene neogene). The evidences of mineralization are in the form of sulfide minerals such as, chalcopyrite, pyrite, arsenopyrite and secondary copper minerals such as malacite especially around the fault zones and near the dikes as veins and veinlets. Plenty of industrial soil is founded in extensive areas of the south and southwest of this region as well. The results from chemical analysis of stream sediments indicate an unusual assay for the following elements, As, Sb, Pb, Fe, Sn, Ni, Co, Ba, and B. The soil samples taken also approve this abnormality. Chemical analysis show the presence of Copper in all samples while the maximum amount reported was 4910ppm. Within the same samples, there was 4950ppm Pb, 1550 Zn, 2440ppm As, and 189ppm U measured at most. The samples taken were from mineral veins containing 1.47ppm Cu, and 2114ppm lead, and 234ppm Arsenic that designate the odd concentration of the above elements. Amount of gold has been reported as 21ppb at most and even less in the other samples. The strategic significance of this region, in addition to the frequent evidences of mineralization along west (Gold in Tank Darreh and Antimony in Sirzar area) demand more detailed investigations for this province.
