Abstract :

Karghan Area is located in East Azarbaijan province, southeast of Tabriz and northwest of Bostanabad city. Based on the division of the structural zones of Iran, it is part of the Alborz-Azarbaijan zone. The most important geological units in the studied area are shale, marl and limestone (Cretaceous), Sahand volcanic products of the age of Pliocene-Pliocoscene, Granitic intrusive, Gabrodiorite and Monzogranite, old terraces and Quaternary sediments. Regarding the spread of the area, 29 geochemical stream sediment samples and 29 heavy mineral samples were taken from the places. The anomalies of arsenic, barium, copper, lead and zinc in the region are represented by their statistical distribution type. The most important heavy minerals with lithological origin were zircon, amphibole and pyroxene. Heavy minerals of pyrite, magnetite and hematite are attributed to the mineralization holes. Heavy mineral studies indicate occurrence of malachite-copper mineralization in the region. Considering the observed anomalies in the stream sediments and heavy minerals, it is recommended detail exploration in the area.
