The hydrothermal sedimented Maanqiao Pb-Zn deposits in middle Tianshan of Xinjiang formed purple fluorite-sphalerite veins which cut through the earlier bedded ore bodies in late metallogenic stage. The hom-ogeneous temperature of the vapor-liquid L-V type fluid inclusions in purple fluorite and sphalerite shows the characters of bimodal distribution and mainly distribute in 140��260�� and 260��442��, and some inclusions ptemperatures are higher than 470��, which indicates the metallogenic fluids composed of two temperature ends including medium-high and low temperatures. The salinity of these vein ore metallogenic fluids is fall into two groups of 1.91 ��6.30 Wt% (NaCl) and 11.93 ��21.82 Wt% (NaCl). The study of laser Raman spectra reveals the main compositions of the gaseous phases in vapor-liquid L-V type of purp le fluorite are some low molecular alkanes (CH₄ , C₂H₆, C₃H₈ ) , aswell as little H₂S and N₂. The fact shows the hydrothermal fluids forming the vein type ores are the mixed by the medium-high temperature magmatic vapor-liquid and the oilfield hot brine with low temperature and high salinity.
