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.
