Matuyama-Brunhes转换期间古地磁场的测定

本文报道由山东蓬莱铜井玄武岩剖面测定的Matuyama-Brunhes转换期间古地磁场测定结果,在此基础上,对地磁场处于极性转换期间的特征作了分析研究,并对造成虚地磁极(VGP)处于低纬度的机制作了新的探讨。     

TRANSITIONAL FIELD BEHAVIOUR FOR THE MATUYAMA-BRUNHES

Paleomagnetic study from Tongjing basalts, Shandong Province, China, provides a record of the transitional field behaviour for the Matuyama-Brunhes. Based on the record the transitional field configurations are studied. The reasons that make the virtual geomagnetic pole (VGP) at the low latitude are researched.
