Abstract
Two national stalagmite standards (GBW04412, GHW04413) and one international coral standard (RKM-4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of (234U/238U)act, (230Th/234U)act and age are all consistent in error range with the standard values obtained by using α spectrometry.
