Uranium-series dating provides radiometric age for the 10–105 year timescales, which is used as a powerful dating method for the geological, climatological, and archeological research. In this paper, we review the methodology and its history of U/Th dating, and the recent climatological researches based on the U/Th dating of carbonate samples.

Key words: uranium–thorium dating; corals; seawater; speleothems; climate change
