Abstract :
Environmental problems of heavy metals are especially important. For sustainable development of mining industry environmental aspects need to be identifed it. The purpose of thisresearch is study of gold genesis and accompanying elements in Siah Jangal region in Sistan andBaluchestan province with attention to contaminating elements of the environment. The studyarea near the sarkahnow village located in north volcano Taftan in South East of Iran in 120 kmsouth East of Zahedan in Sistan and Baluchistan province In geological prospect, the exploratory region of Siah Jangal – Sarkahnow is located in flishi zone of east of Iran and the adjacentof one of the active tectonomagmatic centers of Iran. This area includes flish sediments andophiolitic rocks with Upper Cretaceous age and Paleocene، which between Afghan (Helmand)and Lut block is located. In order To evaluate the contamination of heavy metals in the regionas a systematic sampling was performed. After preparation of the samples were analysed. Theresults were compared with World Health Organization standards and were determined that theelements Cd, Pb, Ni, As contamination in the area and fortunately Hg element does not create alot of contamination. With using this results were depicted the zonation maps of contaminationof elements including As, Pb, Ni, Hg, Cd in this region and was delineate that these elementscaused to contamination in this region. The maps showed that the mentioned elements are causing contamination of the area
