dc.description.abstractThe Meishucun secton has been recommended as an international candidate stratotype secton of the Precambrian-Cambrian boundary. The paper deals with the palaeomagnetic study on the section. A total of 159 palaeomagnetic samples were successively collected from the platform-facies sequence of carbonates and phosphates at the section. Thermal demagnetization results indicate a great majority of the rocks at the section have been strongly overprinted by recent magnetic field, but 57 samples have preserved remanent magnetization with antipodal directions (mean D /1 = 4.2 ° / 7.1 °, K= 9, Α 95 = 6.6 ° ). Baaed on calculation, the location of the palaeomagnetic pole was at 68.8 ° N and 270.7 ° E, which is different from any palaeopoles obtained from younger Phanerozoic rocks in South China. The results reveal a polarity zonation which includes at least 9 reversal events. A comparison of China' s magnetostratigraphic records with those from Siberia, Australia and the western U.S.A. shows that all the sections are characterized by frequent polarity reversals'.en_US
