Abstract
Cu Pb Zn polymetallic deposit in Suihechagan area of Inner Mongolia is a typical hydrothermal depos-it. It locates in the southen section of Daxing'anling metallogenic belt, and Erlian Wudongqi Fe Cu Mo multi metal metallogenic prospect areas in Inner Mongolia. Through study on fluid inclusions in this deposit, it is found that this deposit can be divided into two metallogenic stages: early stage is in medium high temperature phase (320~380℃) and the late stage is in low temperature phase(140~160℃). The trapping temperature of inclu-sion also has two peaks, and the deposit belongs to medium high temperature hydrothermal type. Two peak values also exist in salinity:the first peak scope is 0% ~4% and the second peak is 5% ~9 . 6%. Fluid pressure value is 22. 6~101. 4MPa, and the average value is 59. 9MPa. The average depth of ore forming is 1. 95km below the surface at that time, so this deposit belongs to medium-deep type deposit. The Metallogenic fluid is medium high temperature type, medium voltage, low salinity on the whole. Two metallogenic stages are corresponding with two tectonic movements. Ore bodies are controlled by fractural structures and belong to typical fault control vein de-posit.关键词
