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.
