REE and microthermometric analyses of fluid inclusions in the Jinding Pb-Zn deposit show that homogenization temperature of ore-forming fluid is at 54℃~309℃ and 143℃ in average,and its salinity(ω(NaCl)) is at 1.6%~18.0% and 6.0% in average.
On the base of fluid inclusion analyses,two ore forming fluids are deduced from ores of Xitieshan Pb-Zn deposit. Banded ores are formed in middle-low temperature(182℃～229℃),low salinity(5.3%～21.9%),density <1×10~3kg/m~3,weak acid,and weak reduction environment condition.
Study indicates the following: the gas phase composition in fluid inclusions of all deposits in the district is of CO2-N2-CO-CH4-H2 type, but in comparison with lead-zinc deposits the CH4 value in different mineralization stages of the Baguamiao gold deposit is notably high, while its f o2 and f s2 values are low;
In this paper the vein lead zinc deposit modeling method by researching construction of the variogram, selection of the correct estimation method and parameters by using the search ellipsoid as well as the geological assurance of evaluated resource/reserve classification was discussed.
