| 摘 要： | 拉么铜锌矿床不同成矿阶段形成的主要矿物黄铜矿和闪锌矿，其化学成分、晶胞参数、显微硬度、反射光谱和红外光谱等特征的变化，反映了与其形成时的温度密切相关。矿石中黄铜矿和闪锌矿的硫同位素组成特征，与龙箱盖花岗岩极为近似，成矿物质可能来自花岗岩。

| Abstract: | Chalcopyrite and sphalerite are the major minerals formed in different mineralization stages in Lame copper-zinc deposit, the characteristic varieties of their chemical composition, unit cell parameter, microhardness, reflection spetra and infrared spectra etc. have close correlation with their forming temperature. The compositional characteristics of sulfur isotopes in chalcopyrite and sphalerite ore is quite similar to that of Longxianggai granite, so its metallogenetic substances probably came from granite. |
