| He, Ar Isotope Characteristics and Rb-Sr Dating of the Xintianling Skarn Scheelite Deposit in Southern Hunan, China |
| The Xintinling scheelite deposit, located in the northern contact zone of the Qitinling pluton, is a large-size skarn deposit. So far only very insufficient work has been done in this deposit. In this paper, He and Ar isotopes of fluid inclusions in pyrite was studied, and the ratio of 3He/4He obtained is 4.08 Ra (Ra=1.4×10-6, modern atmospheric ratio), which is significantly higher than that of crustal fluids (0.01～0.05 Ra), suggesting that ore-forming fluids contain not only crustal-derived He but also ab... |
