| 摘 要： | 通过对成矿地质条件进行分析,对地层、构造、岩浆岩与成矿的关系进行探讨,对矿床形成的控矿因素及矿床成因进行分析和总结。研究结果表明:矿区内与成矿有关的地层主要为三叠系中统月山组(T2y)含膏盐白云质灰岩和下统南陵湖组(T1n)灰岩;控矿构造主要为月山岩体与围岩的接触带构造体系;成矿母岩主要为来自于上地幔的中酸性钙碱性燕山早期月山岩体;岩浆带来了大量的成矿流体、成矿物质和巨大的热能,是成矿的先决条件;构造为岩浆的侵位和就位以及成矿流体的运移和沉淀提供了良好的通道和场所;地层主要以其有利的岩性参与了成矿活动;矿体形态主要为透镜状、似层状,矿石组构主要为交代结构和块状、稠密浸染状构造,成矿作用主要为接触交代作用,围岩蚀变主要为石榴子石、透辉石等矽卡岩化及大理岩化,认为矿床的形成与燕山早期岩浆活动有密切关系,矿床成因属于以接触交代作用为主形成的矽卡岩型铜多金属矿床。

| Abstract: | The relationship between mineralization and strata,structure,magmatite rock of Longmenshan Cu-polymetallic deposite was researched based on the analysis of geological conditions.The ore-controlling factors and genesis of deposit were summarized.The results show that the strata concerned with mineralization are dolomitic limestone with thin layer of gypsum of middle Triassic Yueshan group(T2y) and limestone of lower Triassic Nanlinghu group(T1n);the ore-controlling structures are contact zone between Yueshan... |
