Paleomagnetic results of Paleozoic and Mesozoic rocks from Xingshan-Zigui section in Hubei province, South China

The paleomagnetic reconnaissance study of the Paleozoic and Mesozoic sedime ntary locks from the Yangtze Block (YZB) was made to conduct the Apparent P olar Wander Path (APWP) of the YZB during the Phanerozoic. A total of 825 s amples from 84 sites were collected from a continuous section along the Xia ngxi River valley in Xingshan and Zigui counties in Hubei Province, norther n margin of the YZB. Stepwise thermal/alternating demagnetization isolated well defined characteristic magnetization (ChRM) at a higher temperature in most of the samples, and relatively thermal stability and high coercivity were revealed from these samples. All the ChRMs can pass the fold and/or re versal tests, suggesting that they are probably primary. Therefore, new pol e positions are presented for the YZB.
