众所周知,线性磁异常可以提供海底任何地段在生成时间上的信息,也可使我们得以确定它们生成时的所在纬度位置,即能够对地质历史其一时期的原貌进行古重建。原文著者和等(苏联科学院海洋研究所)在“号”第56航次(1974年)以及“号”第12、21和23航次(1974,1978和1979年)中对海底磁场的研究结果,以及美国和日本的研究资料都表明,海底各种构造单元之上的磁场是互不 It is well-known that linear magnetic anomalies provide information about the time of formation in any section of the seabed, and also enable us to determine the location of the latitude at which they were generated, ie, to reconstruct the original appearance of the geological history for a period of time. The results of a study of the seafloor magnetic field in the No. 56 voyage (1974) and No. 12, No. 21 and No. 23 (1974, 1978 and 1979) of the original author and et al. (Institute of Oceanology, The research data of the United States and Japan all show that the magnetic fields above various seafloor structural units are not
