| Abstract: | In this paper, the principle, the analytical method and the application prospect for the determination of 36Cl in underground water by accelerator mass spectrometry(AMS) are introduced. 36Cl in underground water of quaternary from Changzhou was determined by AMS and the origin of brine water from this area was characterized using chlorine isotopes. The results from 36Cl data show that the ages for the underground water of the 3rd group(Q2) and the 4th group(Q1) from this area are 250 ka and 300 ka respectively.\=\= |
