摘　　要：通过对白垩纪超静磁带 (CNS)期间发生的重要地质事件 ,如大洋缺氧事件 ,大量火山活动以及温度升高等的综合分析 ,并结合地球磁场古强度研究结果 。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.

关 键 词：白垩纪超静磁带 地球磁场古强度 地球深部动力学
