| 英文摘要 | It has been more than 100 years since radioactive He-4 was realized to date mineral age, but using U, Th rich minerals as (U-Th)/He geochronometer was developed as a new low temperature thermochronological method in recent 30 years. The low closure temperature of U-Th-He isotopic system (closure temperature for He-4 in apatite is similar to 75 degrees C) makes it expand the lower limit of medium lower thermochronology (e.g. Ar-40/Ar-39 and fission track). Therefore, (U-Th)/He isotopic dating has been widely used in geochronological studies for sub-surface geological processes. Durango apatite is a commonly used international standard for (U-Th)/He dating. Accurate determination of its age could verify the feasibility of the experimental protocol. (U-Th)/He dating laboratory of Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS) was established in 2013. Four batches of a total 40 Durango apatite grains have been tested in this newly-built laboratory. All 40 age results are in the range of 28.95Ma to 34.11Ma and the peak of the age probability distribution is 31.61 +/- 2.7Ma, which is consistent with the international calibrated ages. Moreover, Th/U ratios of the all 40 grains are in the range of 16.43 to 23.72, which were in agreement with results reported internationally. These results indicate that the experimental procedure we established is accurate and feasible. |
