Abstract: | The results on the Early Paleozoic from the North China Block (NCB) are reported. and a series of reliable poles are selected from the available Phanerozoic data, based on the conventional reliability criteria, e.g. the number of samples, the uncertainty limit, any suspected incomplete demagnetization or overprint and field test (including fold, reversal, conglomerate tests). Especially, paleopole data is excluded if the sampling area suffered from the tectonic (e.g. rotation) and thermal effects. A new Phanerozoic apparent polar wander (APW) path for the NCB is compiled, and its tectonic evolution is discussed. |
