Abstarct: The study area is located between 54◦ to 54 30' longitude and northern 36◦ to 37◦ latitude. This area is part of of lead and zinc belt, north to north- eastern of iran. This belt is extended fron Mojen to Shahmirzad and Ahvana mine, shahmirzad mines are located in this belt . Most of lead and zinc mines in thies belt have bean considered as Mississpian Type. Main purpose of this research is detecting lead and zinc anomaly area. For this reason geologal laxyers (stractural, letology) ,geophysic (air magnetic) and geochimstry of stream sediments were chosen to for combin in GIS environment. For geology point of view, a rocks that include this type of deposits are dolomites limestone and carbonate and also sand stone. Faults and rupture have effects important cantrollerIn the first step , 1:100000 geological sheet maps of Gorgan and Dameghan and location of carbonate rocks and faults were hight highted.. Air magnetic data processing performed by goal for clearness fault in GeosoftS oasis Montay software. In order deter mine geochmical anomaly areas , single, variant and multivariante anoalyses were done. Later probability plot soft ware was waed to calculate the threshhold values for haloes and anomaly the geochmical distripbution maps were waed for GIS Enviroments. Finaly, the informational laxyers were combin fuzzy logic in GIS environment. Were ideutified for the follow up step.in identified potential map ,Damghan Sheet lead and zinc , high-potential zone in 1,2,3 areas in area of 29km2are introduced which are 15% of total identified area in identified potential map,Gorgan sheet lead and zinc,high potential zone in 1,2 area of 9km2are introduced which are 10% of total identified area which are privet of discovery.
