摘要

<P style="MARGIN: auto 0cm" class=MsoNormal>g=EN-US>Located in the Sankuanggou-Duobaoshan tectonic-metallogenic belt of&nbsp;Great Hinggan Mountains, the Sankuanggou Cu-Fe-Mo polymetallic deposit is a typical skarn deposit. Petrographic observation and microthermometric study were carried out for fluid inclusions from garnet at the anhydrous skarn stage (Ig=EN-US>), quartz at the hydrous skarn-oxide stage (g=EN-US>Ⅱg=EN-US>), quartz at the early sulfide stage g=EN-US>Ⅲg=EN-US>) and calcite at the early late sulfide stage (g=EN-US>Ⅳg=EN-US>). Studies show that their homogenization temperatures vary from 152 g=EN-US>℃g=EN-US> to 478 g=EN-US>℃g=EN-US>, their salinities are 1.57~58.02 wt% NaCl, and their densities range from 0.64 g/cm³ to 1.18 g/cm³, thus belonging to the ore-forming system of medium-high temperature, medium-high salinity and medium density.pace prefix = o ns = "urn:schemas-microsoft-com:office:office" />p>p>
