第四系某些剖面的古地磁研究和我国下更新统顶底年代的探讨

Abstract: It has been known that the geomagnetic field reversed several times during the past 4.5m.y. and so it is possible to correlate some Quaternary formations basing upon the geomagnetic polarity time scale. It may then be considered as a new approach to the Quaternary stratigraphic study.In this paper the basic theory, sampling and experimental procedures of paleomag-netism in the Quaternary stratigraphic research have also been introduced on the results of 11 sections and 5 cores during the last years in China. It is tentatively proposed that the boundary of N2-Q1 in China has an age of about 3m.y. while the boundary of Q1-Q2 gives age of 0.69m.y..

摘要: 本文概略地介绍了第四纪沉积地层古地磁学研究的基本原理、野外采样及实验方法。文中综合对比了我国近几年来测量的十一个地层剖面和五个钻孔剖面的结果,并对第四系底界(Q1与N2)以及Q1与Q2年代界限进行了初步讨论。
