   Abstract
   The study area is located in Azarbaijan-e Gharbi province, west of Orumiyeh Lake. In this area which is the westernmost section of Central Iran, Precambrian metamorphic rocks are cropping out in reliefs that surrounded by late-Precambrian to Holocene deposits. The basement is composed of meta-volcanic rocks including marble, amphibolite, and other undivided metamorphic rocks. The basements in covered by Silvana formation, that its lithology is similar to Kahar formation. Other rock units include equivalents of Cambrian Barut, Zagun and Lalun formations. Permian rocks that unconformably cover the older rocks, are widespread in the area. Laterite lenses exist in the Permian rocks. Upper Cretaceous rock units are shale, ophiolitic complexes and clastic rocks. No geochemical sampling was done in the project.
   Orumiyeh, Gangajin and Dustan sheets contain several mineral deposits, some of which require more exploration:
   1- Qayduk copper indication
   2- Karim-Abad copper indication
   3- Shirvani copper indication
   4- Khaneqah-e Sorkh iron and phosphate indication
   5- Khanik iron
   6- Iron and phosphate indication at west of Mamakan
   7- Iron and phosphate indication at northeast of Gachi
   8- Iron and phosphate indication at Rigabad
   9- Iron and phosphate indication at Kuran Valley
   10- Torshab mountain iron and phosphate indication
   11- Iron and phosphate indication at east of Gonbad village
   12- Mamakan Iron and phosphate mine
   13- Silica indication at southeast of Rigabad
   14- Silica indication at Bani Valley
   15- Silica indication at Omarabad
   16- Silica indication at Aq-Chekal
   17- Silica indication at Sheikh Bazid Dagh mountain
   18- Bauxite of Neychalan
   19- Bauxite of Bani Valley
   20- Altered intrusions of Mangul, Gale-Khar, Khushalan, Sufikanun, Shekoftik-e Oliya and Sofla, Sinabad, Bohle, and Bohle-e Seyedan
   21- Golmankhaneh pumice and pozzolan
