Characteristics and genesis of ore tube structure of Tamu zinc-lead deposit, southwest margin of Tarim Basin, Xinjiang
新疆塔里木盆地西南缘塔木铅锌矿床矿石管状构造特征与成因

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.
