| 摘 要： | 古地磁或稳定同位素方法为提高沉积物定年精度提供了可能，但若将两种方法在很多地点大范围应用是不可能的。本文采用了来自黄河中游河流阶地的黄土磁化率数据，建立一种与海洋氧同位素记录相互关联的年代一深度关系，并且为黄土堆积物提供了一种较高精度相对定年方法。

| Abstract: | Even though paleomagnetism method and isotopic tecchnology can provide us with the possibility of the accura- cy of the geologic age for loess, it is impossible to apply the methods mentioned in a wide range of areas with a large num- ber of survey points. Data of magnetie susceptibility were adopted from the terrace loess in the mid-reach of the yellow River, and a time-depth relationship that is correlated to the marine oxygen isotopic record was established. Therefore, a new geological dating method with high accuracy for loess formation was introduced in this paper. |
