洋壳磁化率一直用来对海洋磁异常进行解释。但是,1981年Harrison和Carle分析了三条磁测剖面(一条位于大西洋,两条位于太平洋),并且指出根据洋壳的传统磁模型,不能解释中波长(65—1500Km)的磁异常。他们提出最好把上地慢作为这些异常的
Magnetic susceptibility of the oceanic crust has been used to explain marine magnetic anomalies. However, in 1981 Harrison and Carle analyzed three magnetic profiles (one in the Atlantic Ocean and two in the Pacific Ocean) and pointed out that the magnetic anomaly at medium wavelengths (65-1500 km) can not be explained by the traditional magnetic model of the oceanic crust. They suggested that it would be best to slow them down as these anomalies
