| Abstract: | Magnetostratigraphy has been used to study typical sections in northern China in the interval 0~5. 30 Ma B P. A magnetostratigraphic sequence has been established. The Brunhes normal polarity zone and Matuyama reverse polarity zone were recorded in Chinese loess. The Jingle red clay (consists of red clay in the Jingle section, Yulin section and Lantian section) corresponds to the Gauss normal polarity zone and Gilbert reverse zone in the interval 2. 50~5. 30 Ma as well. The Sanmen Formation recorded the lower part of the Matuyama zone, and the Youhe Formation recorded the Gauss zon? The deposits of the Nihewan lake basin can be compared with the Brunhes zone, Matuyama zone and Gauss zone. In the Yushe basin, the Gauss zone and Gilbert zone were recorded in the Macegou and Gaozhuang Formations respecitvely. In the Kuqa area of Xinjiang, the upper part of the Xiyu Formation recorded the lower part of the Matuyama zone, while the lower part recorded the Gauss zone, and the Kuqa Formation recorded the Gilbert zone. |
