| 摘 要： | 以安徽铜陵凤凰山铜矿床为例,通过对成矿流体特征的研究以及碳、氢、氧同位素分析,探讨矿床的成矿机制,分析成矿流体性质以及成矿流体来源。凤凰山铜矿床石榴子石、石英和方解石普遍发育流体包裹体,其类型为V-L型、V-L+S型、V-L富气相型和V型。石榴子石、石英和方解石中的流体包裹体分别集中于3个区,其流体包裹体的温度和盐度区间代表成矿流体演化的3个不同阶段。成矿流体经历了从高温度、高盐度向低温度、低盐度的持续演化过程,与成矿作用阶段基本对应,降温、流体沸腾是导致流体中巨量铜元素卸载的主要因素。氢、氧同位素组成表明成矿流体以岩浆水为主,可能在成矿晚期混有少量大气降水。

| Abstract: | This study takes the Fenghuangshan copper deposit as an example to examine the metallogenic mechanism,the nature and origin of ore-forming fluid using the characteristics of metallogenic fluid and C,D and O isotope analysis.The Fenghuangshan deposit contains garnet,quartz and calcite in which fluid inclusions were well developed.The fluid inclusion can be classified into V-L type,V-L+S type,V-L rich gas type,and V type.Most of the fluid inclusions in garnet,quartz and calcite are concentrated mainly in thre... |
