在30多年前,人们通过海洋磁异常成功地解释了海底扩张和板块运动的过程。从而导致了板块构造学的一场变革。近年来由于高精度磁测技术的应用和磁性解释水平提高,人们又开始借助海洋磁异常对洋壳构造和洋壳磁性层进行深入地研究,其目的就是要揭示出洋壳构造演化的过程,以及地磁场活动变化的规律。本文对世界上若干典型地区的海洋磁异常特征进行了解释,并提供出了未来进行高精度海洋磁性研究需要发展的几项高新技术及方法。
More than 30 years ago, people successfully explained the process of seabed expansion and plate movement through marine magnetic anomalies. Which led to a change of plate tectonics. In recent years, due to the application of high-precision magnetic measurement technology and the improvement of magnetic explanation, the oceanic magnetic anomalies have begun to conduct an in-depth study of the oceanic crust structure and the oceanic crustal magnetic layer. The purpose of this study is to reveal the evolution of the oceanic crustal structure, Changes in magnetic field activities. This paper explains the marine magnetic anomalies in some typical regions of the world and provides some high-tech and methods that need to be developed in the future for the study of high-precision marine magnetic properties.
