湖南省宁乡县斋家冲矿区锰矿床特征及成因

Manganese Deposit Characteristics and Genetic Significance in Zhaijiachong Mining Area,Ningxiang County,Hunan Province

以宁乡县斋家冲矿区锰矿床为研究对象,通过对宁乡县斋家冲锰矿的区域地质特征、矿区地质特征、矿体地质特征、矿床成因的研究分析,认为宁乡县斋家冲锰矿床原为生物化学沉积,由于区域变质作用和中生代岩浆侵入影响而发生改造,矿床类型应属沉积变质型锰矿床。同时认为该地区成矿地质条件好,具有一定的找矿前景。

The paper takes the manganese deposit in Zhaijiachong mining area of Ningxiang County.Through the analysis and study of the regional geological characteristics,geological characteristics,ore body geological characteristics and genesis of the manganese deposit,it considers Zhaijiachong manganese deposit belongs to biochemical deposit.Since the regional metamorphism and Mesozoic magmatic intrusion,the deposit is changed.Simultaneously,the ore forming and geologic condition is good so that it has certain ore prospecting potential.
