古地磁学的研究已成为人类了解地球演化的一种手段。过去磁场的记录: 岩石的磁化强度记录着岩石获得磁性时的地磁场方向。我们借助于它可了解过去地磁场的性质,确定取样处过去地磁场的磁极。古地磁研究的主要目的之一是测定原生磁化强度。次生磁化强度本身意义不大,但它可帮助把岩石磁化历史与地质历史结合起来进行古地磁解释。古地磁地层厚: 地磁场的翻转是形成古地磁地层学的基础。因为全球磁场同时翻转,提供了全球时间界
Paleomagnetism has become a means of understanding the evolution of the earth. Past Magnetic Field Record: The magnetization of a rock records the direction of the geomagnetic field when the rock acquires magnetism. With it, we can understand the nature of past geomagnetic fields and determine the poles of past geomagnetic fields at the sampling site. One of the main purposes of paleomagnetic research is to determine the primary magnetization. Secondary magnetization itself is of little significance, but it can help explain the palaeomagnetic interpretation by combining the history of rock magnetization with geological history. Palaeomagnetic stratum thick: the reversal of the geomagnetic field is the basis of the formation of ancient geomagnetic strata. Because the global magnetic field flip at the same time, providing the global time world
