摘　　要：对采自内蒙古自治区土默特左旗上达赖村附近的大青山南麓山前断裂带上 5 个钙质古土壤样品和 1 个陶片样,分别用 NaOH 溶液将古土壤样品分离出胡敏酸、胡敏素和古土壤全碳以及无机碳酸盐等不同组分,对这些组分进行 C 年代测定,同时对陶片进行热释光的年龄测定,以探讨古土壤的中不同组分的 C 测年可14靠性。Five paleosoil samples and a piece of pottery collected from a trench wall at Shangdalai village, near Tumotezuo county, located in the southern margin fault of Daqing Mountain, inner Mongolia, have been dated by radio-carbon dating and thermoluminescence dating, respectively. The radiocarbon age of total carbon, different organic fraction such as humic acid and humin separated from paleosoil and carbonate in the soil were obtained. These ages were then compared with to evaluate the reliability of the radiocarbon dating age of each fraction.
