摘　　要：韩家山锰矿位于南秦岭磷锰成矿带,属陕西省重要的磷锰资源地,矿床赋存于震旦系陡山沱组第一、二岩性段内,赋矿岩石为白云质灰岩,成因类型为浅海相变质沉积型碳酸锰矿床。本文对该锰矿床地质特征及找矿标志进行了总结研究,进一步论述了该地区锰矿成矿规律,对寻找同类型锰矿具有一定借鉴和指导意义。The South Qinling phosphorus and manganese mineralization belt is a significant resource area for phosphorus and manganese in the Shaanxi Province,and the Hanjiashan manganese deposit is located in the central part of this belt.The deposit is a shallow marine metamorphic sedimentary manganese carbonate deposit that occurs in various lithological segments of the Sinian Doushantuo Formation,with the host rock being composed of dolomite limestone.This study aimed to explore the ore-forming geological characteristics and prospecting indicators of the Hanjiashan manganese deposit,summarize and analyze the ore-forming laws of similar manganese deposits in the region,and provide a basis for searching for such deposits in the South Qinling phosphorus and manganese mineralization belt.This research is based on the geological background and characteristics of the Hanjiashan manganese deposit,and it is hoped that the findings will assist in field geological work.
