Xx. Zhao et al., SILURIAN AND DEVONIAN PALEOMAGNETIC POLES FROM NORTH CHINA AND IMPLICATIONS FOR GONDWANA, Earth and planetary science letters, 117(3-4), 1993, pp. 497-506
We have obtained paleomagnetic results from Silurian and Devonian rock
s on the western margin of the North China Block (NCB), ages which pre
viously were thought to be unrepresented throughout North China. High
unblocking temperature components of magnetization isolated from both
the Silurian and Devonian strata pass fold and reversal tests, suggest
ing that they are primary remanence. The corresponding paleopoles, at
228.4-degrees-E, 26.2-degrees-N (Silurian) and 228.7-degrees-E, 34.2-d
egrees-N (Devonian), imply low paleolatitude positions of North China
during the middle Paleozoic, probably adjacent to east Gondwana.
