High Precision Thermal Ionization Mass Spectrometric Dating of Corals and Its Application to Paleo-Environmental Study

摘要

Global change has become a hot spot in Quaternary geology, and high\|precision, high\|sensitivity dating is also an urgent problem which needs to be solved. This paper presents some achievements in U\|series dating of marine corals by thermal ionization mass spectrometry (TIMS) and its application to the study of paleo\|environments. Recently, coral samples were determined for their ages on a MAT\|262 mass spectrometer and satisfactory results have been obtained.
