对捷克Znojmo剖面末次间冰期以来黄土-古土壤序列进行了较为详细的岩石磁学和X射线衍射实验研究, 结果表明捷克黄土-古土壤磁化率变化与中国黄土高原风成沉积物具有相似的特征, 即土壤化作用使磁化率升高. 磁化率随温度的变化特征和等温剩磁测定以及X射线衍射实验揭示出Znojmo剖面黄土和古土壤的主要磁性矿物是磁铁矿, 并含有少量的磁赤铁矿、赤铁矿和黄铁矿或磁黄铁矿以及针铁矿. 磁化率各向异性研究表明, Znojmo剖面黄土和古土壤的磁线理小于磁面理, 这说明磁化率椭球体为压扁形, 最大轴的方向呈现随机分布特征, 不能指示大气传输尘埃沉积时的古风向.
The magnetotactic and X-ray diffraction experiments of loess-paleosol sequence from the last interglacial period of the Znojmo section in Czechoslovakia have been carried out. The results show that the change of the susceptibility of loess-paleosol in the Czech Republic is similar to that of the aeolian sediments in the Loess Plateau , That is, the soil magnetization increases.The magnetic susceptibility changes with temperature and isothermal remanent magnetization and X-ray diffraction experiments reveal that the main magnetic minerals in the loess and paleosol of the Znojmo section are magnetite and contain a small amount of magnetic Hematite, hematite and pyrite or pyrrhotite and goethite.The magnetic susceptibility anisotropy study shows that the magnetic lineage of the loess and paleosol in the Znojmo section is less than that of the magnetite, indicating that the susceptibility ellipsoid For the flattened shape, the direction of the largest axis shows a random distribution, can not indicate the direction of the ancient wind when the atmospheric transmission of dust deposition.
