Abstract: Two main types of methods for relative paleointensity study are introduced in this paper. One is traditional normalization method and the other is pseudo-Thellier method.First, general principles and procedures of the two methods are summarized, then selections of different normalizers in traditional normalization method are discussed, and also comparison is done for the relative paleointensity results from the two methods used, especially in Ontong Java Plateau (OJP) sediments.It is predicted that there is broad perspective of relative paleointensity study in dating marine sediments and probing the interior of the Earth. -
