Characteristics and genesis of ore tube structure of Tamu zinc-lead deposit, southwest margin of Tarim Basin, Xinjiang
|
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.
