摘要: 本文根据嘉荫盆地、依兰—伊通地堑、抚顺盆地等6个盆地中2个露头剖面、18个钻井剖面采集的493块第三系古地磁样品的测试结果,得出乌云组极性序列相当于26~27极性时,永吉组、双阳组相当于18~24极性时、虎林组相当于10~13极性时,古纬度比现今偏南4°~5°.

Abstract: Palaeomagnetic measurements were carried out for 493 samples,which were collected from two outcrop sections and eighteen core sections in the northeast oil-gas-bearing region in China.It is shown that the polarity zones could be correlated respectively with polarity chrons 26-27 for Wuyun formation,18-21 for Jijuntun and Xilutian formations,18-24 for Yongji and Shuangyang formations,and 11-13 for Hulin formation.The palaeolati tudes were 4°~5°lower than its present values.
