摘要:
Study on source of metallogenic material and characteristics of the ore-forming fluid of the Yanlinsi Gold deposit in northeastern Hunan province, China
      The Yanlinsi gold deposit, located in the Eastern district of Xuefeng arc structure belt(The Hunan Section of the Jiangnan Orogen), is a typical gold deposit in northeast Hunan Province. This paper analysis of gold content in different geological bodis, study on H-O isotope geochemistry, Sr isotope geochemistry and composition of ore-forming in gold-bearing quartz. This paper proposes that gold is quite rich in the Lengjiaxi Group during the sedimentation.The geochemistry of rare earth element and trace element in ore, altered rocks and unaltered rocks shows high similarity. Ore-forming fluid according the characteristics of Sr isotope geochemistry, H-O isotope geochemistry, and composition of ore-forming in gold-bearing quartz maybe metamorphic fluid. The stud,combined with the geological characteristics, gold content in different geological bodis, geochemistry of rare earth element and trace element, H-O isotope geochemistry, Sr isotope geochemistry and composition of ore-forming in gold-bearing quartz, have been enough to convince the author to believe that the Lengjiaxi Group provides minerals during ore process.
