摘要

华北蓟县剖面串岭构组5个点37个样品的热退磁再研究成果,获得极位为239.1°E和22.2°N,k=82,A₉₅=8.5°,落在已建立的蓟县元古界的视极移轨迹的常州组极和团山子组极之间连线附近,合理而可信.结果还表明测试的(次)火山岩与沉积岩是准同生的,可用作钻石U-Pb法测年对象.

Abstract：

A thermal demagnetization restudy of 37 samples from five points of Chuanlinggou Formation along the Jixian section in North China shows that the pole position is 239. 1°Eand 22. 2°N, K = 82, A₉₅= 8. 5°, which falls near ths connection line between the pole of Changzhougou Formation and that of Tuanshanzi Formation alone the established apparent polar wandering path of Jixian Proterozoic. The result is reasonable and believabls. It is also shown that the tested (sub)volcanic rock and sodimeotary rock are penecontemporaneous products, which might be used to make zircon U-Ph dating.
