| 摘 要： | 江西九(江)瑞(昌)铜金矿田是长江中下游铁、铜、金成矿带的重要组成部分。受环太平洋共振构造带的影响,区内燕山期岩浆活动频繁,形成近30个浅—超浅成中酸性侵入体,主要含矿岩体从早至晚沿石英闪长玢岩→花岗闪长斑岩→石英斑岩方向演化,伴随这一演化趋势,岩体的含矿性也发生相应变化:Au→Cu→Mo,它们直接控制了区内铜、金矿床的转化。

| Abstract: | Jiujiang-Ruichang ore area of copper and gold is an important part of Fe. Cu and Au met-
allogenetic belt in the middle and lower reaches of Yangtze river.
Since affected by circum-Pacific resonant tectonic belt, the magmatic activity of Yanshan
period took place frequently and brought the forming of about 30 hypabyssal- ultrahy-
pabyssal, intermediate- acldic rock bodies. The major ore-bearing rock bodies are of quartz
diorite porphyry-granodiorite porphyry-quartz porphyry from early to late time. With the vari-
ation of this evolution, the commodity in rock bodies changed relevantly: Au→Cu→Mo |
