| 中文摘要: |
| Helium,neon and argon isotope compositions of fluid inclusions have been measured in massive sulfide samples from the Jade hydrothermal field in the central Okinawa Trough.Huid-inclusion 3He/4He ratios are between 6.2 and 10.1 times the air value (Ra),and with a mean of 7.8Ra,which are consistent with the mid-ocean ridge basalt values[3He/4He≈(6Ra~11Ra)].Values for 20Ne/22Ne are from 10.7 to 11.3,which are significantly higher than the atmospheric ratio (9.8).And the fluid-inclusion 40Ar/36Ar ratios range from 287 to 334,which are close to the atmosperic values (295.5).These results indicate that the noble gases of trapped hydrothermal fluids in massive sulfides are a mixture of mantle-and seawater-derived components,and the helium of fluid inclusions is mainly from mantle,the nelium and argon isotope compositions are mainly from seawater. |
