Abstract: In this paper the authors discuss the reliabiliy of radiocarbon ages of black clays filled in Zhangshanzha ground fissures and the ages of calcareous concrete outcroped on both sides of the fissures. In addition,the stratigraphical division of late Quaternary,the ages and formation mechanism of the ground fissures have been discussed as well.
