九瑞矿集区构造及岩浆活动十分强烈,从晋宁期到喜马拉雅期都有发育,但主要的成矿时期为燕山期,与成矿密切相关的构造主要为NW和NEE向,其次NNW-NNE向,它们构成菱形网格结构,控制本区岩浆岩和铜金矿床的产状及分布。
九瑞礦集區構造及巖漿活動十分彊烈,從晉寧期到喜馬拉雅期都有髮育,但主要的成礦時期為燕山期,與成礦密切相關的構造主要為NW和NEE嚮,其次NNW-NNE嚮,它們構成蔆形網格結構,控製本區巖漿巖和銅金礦床的產狀及分佈。

Tectonic and magmatic activities of Jiujiang-Ruichang ore concentrated area are very strong, have developed from Jinningian to Himalayan. But Yanshanian is the main mineralization period, the structure related to mineralization is mainly NW and NEE, secondly NNW and NNE, they constitute the rhombus grid structure, and control the occurrence and distribution of magmatite and copper-gold deposit in this area.
