摘要
对新疆奥尔托喀讷什锰矿床的地质特征及成因进行了研究,结果表明:锰矿体呈层状、似层状和透镜状产于上石炭统喀拉阿特河组第三岩性段泥质灰岩中;矿石矿物以菱锰矿为主,矿石类型简单;矿石结构以微晶结构和交代结构为主。其工业矿石类型为低铁中磷酸型碳酸锰矿石,矿石品位高、变化小,普遍具有后期热液改造的痕迹,为浅海沉积后期热液改造型富锰矿床。
The geological characteristics and genesis of Ortokanesh manganese deposit in Xinjiang were studied.The results show that the manganese ore bodies occur in the argillaceous limestone of the third lithologic member of the Kalaatahe Formation of the Upper Carboniferous in stratiform and stratiform in lentiform.The ore minerals are mainly rhodrosite.We think the ore type is simple and the ore structure is mainly microcrystalline structure and metasomatic structure.The industrial ore type is low iron medium phosphate type in manganese carbonate ore.Its ore has high grade and little change and it generally has the traces of late hydrothermal reformation,which is the type of rich manganese deposit in the late hydrothermal reformation of shallow sea deposition.
