甘肃临夏盆地东山顶剖面沉积物磁组构特征研究

Study on the Magnetic Fabric Features of the Samples Taken from Dongshanding Profile in LinXia Basin,Gansu Province

测量了位于青藏高原东北边缘的临夏盆地东山顶剖面各段不同沉积相沉积的磁组构参数，认为造成各段之间差异的主要原因之一是不同的沉积环境条件，其风成黄土段的特征主要同其母质来源方向有关，而其余各段的差异可能同青藏高原阶段性的隆升及由此造成的环境变化有关．

The magnetic fabric features of the samples taken from four parts of Dongshanding Profile in Linxia basin, which locates at the north eastern fringe of Qing Zang Plateau are (liverse. The diverse sedimental environmental conditions may probablly account for the difference. The characteristics of the eolian loess part of this profile may relate to its source parent material, the others, however, probablly to the uplifts of Qing-Zang Plateau or the environmental changes deduced by this plateau.
