   Abstract
   The study area is located in the Kerman Province, between 56 30' to 57 E and 29 30' to 30 N. It involves two mountain ridges extending from NW to SE at north and south of the area. The area is mountainous with several picks more then 3000 m a.s.l. this sheet belongs to the Orumiyeh-Dokhtar structural zone with rock units from Cretaceous sedimentary deposits to intrusive to volcanic rocks. The oldest rocks are of the Late Cretaceous flysch type deposits. They include green to gray marl with sandstone and siltstone intercalations. There are great dykes of Neogene, basaltic in composition. The Eocene deposits include volcano-sedimentary rocks that started with a basal conglomerate.
   The data layers used in this project for mineral mapping include:
   - topography data of 1:50000 maps
   - 1:100000 geology map
   - Hammer prospection and metallogeny data
   - Airborne geophysics data
   - Geochemical data including geochemical anomalies, heavy minerals, and favorable zones
   - Remote sensing data including alteration zones and lineaments
  
   We used the weight of evidence and logistic regression analyses for compilation of above mentioned data layers. By these methods several anomalies were identified that checked and sampled in the field. Among these anomalies, anomalies umber 2, 3 and 4 are similar and probably correlate with a unique fault zone. They have barite veins. Diagrams number 11, 12 and 13 show the result of geochemical analysis in the anomalies 2, 3 and 5 for copper, lead, zinc, gold and silver. Anomaly 1 has great extent, but low chance of mineralization. Anomaly number 5 has unsuitable alteration hallow with limited mineralization. Among them, only anomaly number 2 is proper for more detailed studies.
