摘要
永平铜矿黄铁矿、黄铜矿的化学成份特征以及矿物测温和石英包体成份分析特征表明成矿经历了一个较低温度阶段，但所反映的后期成矿作用的改造特征也非常明显，特征是闪锌矿，其化学成份具明显的后期改造成矿特征，是岩浆热作用的产物。黄铁矿的同生成矿较为明显，闪锌矿的后期改造成矿特征更为明显，而黄铜矿具有明显的沉积改造特征。
Chemical analysis and thermometry of pyrite and chalcopyrite as well as quartz inclusion component in the Yongping copper deposit reveal that mineralization has undergone a lower temperature stage,although remolded features by late-stage mineralization reflected thereof are very obvious. As a result of magmatic hydrothermal process, these remolded features are displayed especially remarkably in the composition of sphalerite. On the other hand pyrite has a more pronounced syndepositional feature, while chalcopyrite is characterized by a sedimentation-remolding origin.
