摘　　要：用裂变径迹法对兰州九洲台黄土中同生石膏矿物作了年龄测定,得出年龄值为1.46—1.52Ma,从而推断九洲台黄土形成时代应早于1.5Ma。The application of the fission track dating to the Jiuzhoutai loess profile in Lanzhou shows that the intergrowth gypsum on the bottom of the paofile was formed about 1.46 to 1.52 Ma ago, from which deducing that the age of loess accumulation at Jiuzhoutai was more than 1.5 Ma.
