Sediment-Hosted Copper Mineralization in Bavanat Region, Southern Sanandaj-Sirjan, Iran

Sedimentary copper mineralization has been observed in monj and jolany locationsin bavanat (sanandaj – sirjan metamorphic belt). according to current study, the hostrocks for copper mineralization in this area are green sandstones, generally in subarkoseand arkose groups. age of these sandstones is middle jurassic. copper mineralization isobserved in two forms, sulfides form including chalcopyrite, chalcocite, covellite andalso non-sulfide form including malachite, azurite and chrysocolla. sedimentary copperdeposit of bavanat is very similar to redbed type of sedimentary deposits such asnacimiento deposit in usa for many reasons, including the host rock (greensandstone), concomitant rocks (habitual accompaniment with purple siltstone), age offorming, geological environment and the type of mineralization. these similarities canbe useful in supplementary studies. studied sedimentary copper deposits are differentfrom the jian copper mine in terms of attributes such as host rock, age of formation,upper and lower rocks and also the type of copper mineralization. based on chemicalanalysis results, the average amount of copper concentration in the samples was 15509ppm, which confirms the need for additional studies.
