Overview

Geochronology and geochemistry analyze gold mineralization processes in Northeastern Jiaolai Basin.

Key Points

  • To investigate the genesis of the Longkou gold deposit and its similarities to the Northwestern Jiaodong area.
  • Conducted Rb-Sr dating of sericite in situ
  • Performed trace element analyses of pyrite
  • Conducted sulfur isotope analyses of pyrite
  • Obtained sericite Rb-Sr age of 120.9 ± 2.4 Ma for gold mineralization
  • Identified two generations of pyrite with differing δ34S values
  • Noted increase in oxygen fugacity related to fluid–rock interactions
