Abstract : The paper presents data on the paleomagnetic pole position for the Mesozoic and Tertiary, derived from red beds in Xichuan, Yunnan, Hunan, Hubei and Guangdong Provinces. The results obtained by analysis and by comparison with those found from neighbouring countries are summarized as follows: (1) The mean position of the paleomagnetic pole for the Early Tertiary was probably at latitude 78 deg. N, longitude 171 deg. E, and for the Jurassic and Cretaceous was at latitude 59 deg. N, longitude 153 deg. E. Evidently, the paleomagnetic pole has undergone change of position, wandering from low latitudes to high. (2) The middle and upper portions of red beds of the Henyang Basin exibit a reversal of paleomagnetization; hence these rocks are considered to be of Oligocene and Miocene age respectively. Examined by the 'remagnetized arc' method, the magnetizations of all the samples measured are rather stable. (Author)
