摘    要:永平铜矿产于断裂坳陷带中,明显受地层控制。从包裹体特征,硫、氢氧、铅同位素、稀土组成、黄铁矿中Fe、S的组成,围岩含矿性对比等结果可以看出,其成矿物质的主要来源是火山喷流作用带来的深部物质。综合其它的成矿特征,得出永平铜矿的成矿模式:海底火山喷流沉积一混合岩化、动力改造一岩浆热液叠加改造型。

关 键 词:成矿物质来源  矿床成因  包裹体  永平铜矿

Abstract:The Yongping copper deposit is situated in the intracontinental tectono-depression and controlled by stratum. The characteristics of fluid inclusions; S, H, O, Pb isotope compositions; REE compositions; chemical compositions and Fe/S of pyrite;main mineral elements abundance of pyrogenetic rock and periphery rock in Yongping imply that the main ore-forming material came from the volcanic exhalation. Through integrating these indices and other geological evidences, we can conclude that the Yongping copper deposit is multi-period complicated accumulation process of metal elements and the genetic type of the deposit is volcanic exhalation sedimentation-migmatization and dynamic reconstruction-magmatic hydrothermal reform.
Keywords:Source of ore-forming material  Deposit genesis  Fluid inclusions  Yongping copper deposit
