Study on fluid inclisions of Nanjinshan gold deposit of Beishan area,Gansu Province
摘要
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°C), medium-low salinityCNaCleq 6% to 7%)and enrichment of CO2 belonging to Na+ (K+ ,Ca2+ )-Cl" (F~ ) - H2O system. H,O, isotope analysis of gold-bearing quartz is δ(18Oquartz) 12. 2X 10~3 to 15. 8X 10~3 with enrichment of 18O and δ(18OH2o) ~0. 22×10-3 to 7. 44×10-3. This reflects that the ore fluid is of deep source and large volume meteoric water icorporate in the mineralization.关键词
