【Abstract】 Several abnormal geological events, such as oceanic anoxic event, a large number of vocalism and the global climatic warm during Cretaceous normal polarity superchron (CNS) has been described and analyzed in this text. Combined with the result of palaeointensity study, possible links between the Earth’s interior process and its control on the variation of the earth’s magnetic field during the geological time were tentatively discussed.更多还原
