晋陕峡谷大路梁黄土磁组构特征及其指示的古风向
Magnetic Fabrics of Daluliang Loess and the Paleowind Direction Indicated
摘要
Abstract
The essay reports the AMS-based reconstruction of the paleowind direction variations spanning the past 0. 9 Ma in the Jinshan Gorge. The results show that there is resemblance between the previous studies and this profile, while this profile has its special characteristics. The magnetic foliation (F) of almost all of the samples is higher than the magnetic lineation (L) and the degree of AMS (P) is correlative with F greatly, the shape parameter of the AMS ellipsoid is oblate. Magnetic fabrics indicated that a stable prevailing paleowind of NE-SW direction was established over the past 0. 9 Ma and the main direction did not have markedly transformed. This coincidence may imply that the north-south gorge topography might have causally related with the prevailing wind direction in the Jinshan Gorge.关键词
