江西弋阳南家坞锌(锡)矿地质特征及成因初探

Preliminary Study on Geological Characteristics and Genesis of Nanjiawu Zinc (tin) Deposit in Yiyang,Jiangxi Province

对南家坞锌(锡)矿床地质特征、成矿地质条件和矿床成因进行了初步探讨,认为矿床定位受区域性断裂及灵山岩体控制,矿体主要赋存在南华系板岩、变余砂岩等碎屑岩中,矿体呈长带状产于NNW向层间破碎带中。成因类型属构造蚀变岩型锌(锡)矿床,通过进一步加深对矿床成因的认识,有利于扩大该区深部及外围找矿工作。

Based on the preliminary study on geological characteristics,metallogenic geological conditions and genesis of Nanjiawu Zinc （tin） deposit,the author states that deposit location is controlled by regional fracture and Lingshan rock mass,the ore body exists in clastic rock mainly, such as Nanhua System slate,blastosandstone, and occurs in NNW trending interlayer fracture zone as shape of long band. It belongs to type of structural altered rock deposit, with deepening the cognition of deposit genesis;it is benefit for enlarging prospecting in its depth and surrounding areas.
