The host rock of mineralization within the deposit is a part of Sanandaj-Sirjan, Oligo-miocene age. The composition of these rocks is mainly from moderate to basic volcanic units of porphyritic pyroxene andesite that approximately has covered most of the area. The geological sequence of the locality is cut by some stocks and diabasic dykes. Tree zones of alteration were detected from TM satellite images with W-E elongation in area including silisification, prophilitic,phillic, Argillic, quartz-calsedonit-Alunite and advanced argillic alteration. The mineralization displays alteration pattern consisting of a core of residual (vuggy) silica, bordered outward by zones of quartz-kaolinite, alunite and montmorillonite. Some veins have occurred in alteration zones including gold-copper bearing veins in the west area and silver and base metals bearing veins in the middle area. Mineralization studies of alteration in the west area around silica veins by XRD indicated association of quartz, kaolonite, alunite, montmorillonite, jarosite, anatase. Mineralization studies on polished samples of silica veins by optical microscope and scanning electron microscope have showed anatase, tree generation of pyrite, enargite, tenantite, native gold, electrum with some barite and chromium minerals. The composition of veins varied in different veins. The veins are formed of vuggy silica which the vuggs (usually 5-20µm) hosted gold bearing third generation thin pyrite. Oxidation of the sulfides extricated gold in to secondary residual limonite. The type of mineralization, alteration, textures and situation of deposit forming in relation to intrusion bodies shows similarity to an epithermal high sulfidation deposit type with variation of mineralization in veins.
