| Abstract: | Fluid inclusions in quartz vein and mineralized bodies are moderately developed in Nanjinshan gold deposit with small size. They occur mostly CO2 inclusion and two phase （liquid and gas）inclusion. The ore fluid of Nanjinshan gold deposit is characterized by medium-low temperature（160 to 240℃）, medium-low salinity（NaCleq 6% to 7%）and enrichment of CO2 belonging to Na＋（K-,Ca2＋）Cl-（F-）-H2Osystem. H,O, isotope analysis of gold-bearing quartz is δ（18Oquartz）=-0.22×10-37.44×10-3 with enrichment of 18O andδ（18OH2O） =-0.22×10-37.44×10-3. This reflects that the ore fluid is of deep source and large volume meteoric water icorporate in the mineralization. |
