Geological characteristics and prospecting criteria of Hanjiashan manganese deposit in Mianxian County,Shaanxi province,in the northwest margin of the Yangtze block
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.
