摘要
贵州水城宏运锰矿床位于上扬子陆块、鄂渝湘黔前陆褶断带内,利用宏运锰矿普查成果,较详细地总结了矿床地质、矿体地质和矿石特征,区内锰矿体赋存于茅口组第二段中部,呈透镜体、似层状产出,产状与地层一致,深部原生碳酸锰矿石的矿石矿物主要为含锰方解石,次为含锰白云石,脉石矿物为方解石;浅部氧化锰矿的矿石矿物主要为软锰矿,次为含锰方解石,脉石矿物为方解石.矿石结构主要为细-粉-微-隐晶级他形粒状晶体结构,矿石构造以条带状和层纹状为主,Mn平均含量为15.25%.锰矿石自然类型为以含锰灰岩矿石为主,次为氧化锰矿石;矿石工业类型属于低磷低铁碱性含锰灰岩.
Abstract
The Hongyun manganese ore deposit in Shucheng,Guizhou,is located within the upper Yangtze landmass and the E-Y-Xiang-Qian foreland fold belt.Utilizing the results of the Hongyun manganese ore survey,this paper provides a detailed summary of the deposit's geology,ore body geology,and ore characteristics.The manganese ore body is hosted in the central part of the second section of the Maokou Formation,appearing as a lenticular and bed-like body,with an attitude consistent with the strata.The ore minerals in the deep primary manganese carbonate ores are primarily manganese-bearing calcite,with minor manganese-bearing dolomite,and the vein mineral is calcite.The ore minerals of the shallow manganese oxide ores are mainly pyrolusite,with minor manganese-bearing calcite,and the vein mineral is calcite.The ore structure is predominantly fine-powdered,micro-cryptocrystalline,and xenomorphic granular crystal texture,with banded and laminated textures being predominant,and the average Mn content is 15.25%.The natural types of the ore are primarily manganese-bearing chert,followed by manganese oxide.The industrial type of the ore is characterized as a low-phosphorus,low-iron alkaline manganese-bearing chert.
