| 摘 要： | 通过测量张家湾、大路梁两个典型剖面共计125个黄土样品的磁组构参数,初步认为两剖面磁组构特征为正常沉积,受后期扰动较少。其磁化率各向异性指示的古风向表明,该地区近地面主导风向以NE-SW为主,这与本区黄河河谷走向基本一致,应该是峡谷地形所致。

| Abstract: | One hundred and twenty five undisturbed loess samples were collected from Zhangjiawan and Daluliang areas for Magnetic fabrics measurements, The results show that The two section is the normal deposition, less controlled by late disturbance. The anisotropy of loess magnetic susceptibility （AMS） indicates that a stable prevailing palaeowind of NE-SW direction was established .This coincidence may imply that the north-south gorge topography might have causally related with the prevailing wind direction in the Shanshan Canyon. |
