The element zonation characteristics of No. XV ore body in Zhaxikang lead-zinc polymetallic deposit, Tibet

Represented as the most typical sample of lead-zinc mineralization in the Cenozoic tectonic-metallogenesis of Tethys Himalaya, the Zhaxikang lead-zinc polymetallic deposit’s newly discovered No. XV ore body has a third largest scale after the main No. Ⅴ and No. Ⅵ ore bodies. Due to its late discovery time and low research degree, the element zonation research had been conducted to make contributes to geological characteristics of this orebody. The conclusions demonstrate: ① The strata around ore body had a good supply capacity of Pb, Ag and Sb elements, while the enrichment of Zn elements had little to do with the strata. The lead-zinc mineralization was closely related to a complete set of high-medium-low temperature association of elements such as Hg, Ag, Sb, Bi, Pb, Sn, Cd, Cu, Mn, and Zn. ② During the migration upward, ore bearing hydrothermal solution was continuously precipitating and mineralizing without obvious overprinted metallogenic process. ③ There was still certain metallogenic potential at depth. The establishment of the zonation model of No. XV ore body would be a proper response to the Cenozoic tectonic-metallogenesis of Tethys Himalaya under which there was a good representation of the general Pb-Zn mineralization. At the meantime, it was also an important significance deep potential prediction.
