摘要
From the profile which is located in the Hexi Corridor,NW China, 13 samples were collected for conventional 14C dating and 5 samples were collected for AMS 14C dating. The materials used for 14C dating were seeds, mud and wood. Based on the dating results, the authors reconstructed the age framework of Huahai Lake since the Late Glacial period. And then, the authors concluded that the sediments between 0.73～6.83 m were deposited during Holocene. Between 6.83~7.35 m, the sediments were deposited during the early Holocene and the late Younger Dryas. The sediments of 7.35~10.44 m were deposited during the Late Glacial and early Younger Dryas. Based on the mineral analysis of the sediments during the Younger Dryas and late glacial, mirabilite was the main component in the sediments,indicating the low-temperature environment.
