精细地球化学找矿方法的一次实践——以江西九江城门山铜矿外围联盟银金矿化点的发现为例

A practice of refined geochemical prospecting research—a case study of Lianmeng silver-gold mineralized spot at periphery of Chengmenshan copper deposit, Jiujiang County, Jiangxi Province,China

摘要: 结合本次城门山铜矿东南侧联盟银金矿化点的发现，论述了开展精细地球化学找矿的重要性，即遵循"以矿找矿"和铜多金属矿床的时、空套叠成矿作用的准则，以地质为基础，以现代地球化学成矿成晕机制为指导，以勘查地球化学新技术、新方法和高精度的分折测试为支撑，在老矿区的深部和外围开展新一轮的地球化学找矿方法研究。

Abstract: In this paper, combining with the discovery of Lianmeng silver-gold mineralized spot at southeast of Chengmenshan copper deposit, we discussed the importance of carrying out refined geochemical prospecting. That is to follow the criteria of "on the mineral prospecting" and spatial-temporal superposition mineralization of the copper-polymetallic ore deposits, on the basis of geology, guided by modern geochemical ore-forming theory and supported by geochemical exploration of new technologies, new methods and high-precision test, we carried out a new round of geochemical prospecting method research in the depth and periphery of the old mining areas.
