The evolution characteristics of metallogenic fluid in Tongling deposit concentrated district

摘要

Based on the observation of regional mineralized network, the statistics of thermometric data of fluid inclusions, the temperature calculation via ion thermometer method and the corresponding compositional analysis based on the liquid components in fluid inclusions, the analysis of H-O isotopes of metallogenic fluid, three principal features of metallogenic fluid in the Tongling deposit concentrated district, including the phased evolution, the unmixing of poly-phase fluids and the hybrid process of fluids with different origins, are revealed.
