Re-Os Dating for Molybdenite and Characteristics of Ore-Forming Fluids of the Mujicun Copper-molybdenum Deposit in Hebei Province
Based on the Mujicun porphyry Cu (Mo) deposit in different core drilling at different depths in five ore molybdenite Re-Os isotope determination, obtains the pattern age range of variation 143.2±2.2Ma~144.9±2.3Ma, and calculates obtains the isochrone age for 143.8±1.2Ma, may fix a time limit of Mesozoic metallogenic late Jurassic.In addition, according to the ore 124 fluid inclusions indicate that inclusions are mainly gas-liquid two-phase inclusions, gas-rich inclusions containing liquid carbon dioxide solid multiphase inclusions and four types of inclusions, liquid and gaseous components are ingredients mainly H2O, in which gaseous inclusions are also visible CO2; forming temperature is generally in the temperature and salinity of the low salinity.
