本文综述了适用于陆地沉积物的铀系测年方法。α计数技术可以在1 ka至350 ka的时间范围内以± 5%至10%的精度测定碳酸盐和磷酸盐的年代。原子计数方法（质谱法和AMS）大大提高了精确度，并可能增加范围。污染和开放系统的行为问题进行了讨论。在意大利一个洞穴的洞穴沉积物测年中，证实了碎屑污染物的校正。
This is a review of U-series dating methods as applicable to terrestrial sedimentary materials. Alpha-counting techniques allow the dating of carbonates and phosphates with a precision of ± 5 to 10% over the time range from 1 ka to 350 ka. Atom counting methods (mass spectrometry and AMS) substantially increase precision and may increase the range. Problems of contamination and open-system behavior are discussed. Correction for detrital contaminant is demonstrated in the dating of speleothem from a cave in Italy.
