沉积岩磁倾角浅化校正方法

Correcting Methods of Shallow Bias in Paleomagnetic Inclinations in the Sedimentary Rocks

在沉积岩的古地磁数据统计中,记录的磁倾角数据普遍存在浅化现象。通过综合分析E/I法、非滞后剩磁各向异性法和等温剩磁各向异性法原理及其研究实例,总结沉积岩磁倾角校正浅化的一般流程。

In the study of paleomagnetism data from sedimentary rocks,we found that there is a shallow bias of inclination which was recorded by sedimentary rocks generally. Based on the comprehensive analysis of E/I method,the anisotropy of anhysteretic remant magnetization,anisotropy of isothermal remanent magnetism,and their principles and cases,this paper summarizes the general process of correction shallow bias of inclination in the sedimentary rocks.
