| 摘 要： | 通过对塔木铅锌矿手标本和显微镜下光薄片的观察，矿石管状构造特征尤其是闪锌矿等硫化物分布形成的轴对称性管脉，为溶蚀-交代和空隙充填作用的产物，表现为硫化物沉淀伴随白云岩化灰岩溶解而发生，暗示硫化物与溶蚀-交代及孔洞充填这两个过程有关。脉动成矿流体运动成了更为复杂的轴对称性管脉。

| Abstract: | Based on the observation of hand specimens and microscopic scale section samples, the tube structure ores show axissymmetric characteristics in Tamu zinc-lead deposit. This structure is resulted from dissolution and metasomatism, which reflect the sulfide mineralization (sphalerite) and dissolution (dolostone I) are contemporaneous and indicate mineralization relates to two processes dissolution-metasomatism and cavity filling. Moreover, the pulse-styled fluid movement induces the more complex axissymmetric tubes. |
