| 摘 要： | 文章对大别山北麓黄土-古土壤的磁化率各向异性进行了初步研究,结果表明:剖面上部的磁组构参数P、F、L平均值均低于底部的相应值;在磁组构参数F-L、P-q、P-F组合关系图上,上部样品的数据点集中分布于靠近坐标原点的区域,底部的多远离坐标原点;磁组构特征指示了上部为风成沉积而底部为水成沉积。 |

| Abstract: | The anisotropy of magnetic susceptibility of loess-palaeosols from the northern slope of Dabie Mountains is examined.The mean values of magnetic fabric parameters(P,F,L) of the upper part of the strata are less than those of the bottom.In the figures of F-L,P-q,P-F relation,the data of aeolian deposit are mostly concentrated in the vicinity of the coordinate origin,while the data of hydraulic deposit are mostly distant from the coordinate origin.Generally,the magnetic fabric characters show that the upper part of the strata is aeolian deposit and the bottom is hydraulic deposit. |
| Keywords: | Dabie Mountain magnetic fabric loess-palaeosols environmental change |
