摘要
Over 800 paleomagnetic samples were collected from 79 sample localities, ranging inage from Devonian, Carboniferous, Permian to Jurassic for palcolatitude research on theGulzhou terrain. The area sampled covers 13 counties with an area of about 50000 km2. Thepaleomagnetic results obtainal indicate that the Guizhou was at 11. 4°S in Devonian, 4. 5° -9. 3°S in Carboniferous, 2. 6°- 4. 5°S in Permian, 14. 8°N in Triassic and 24. 5°- 26. 0°N inJurassic. In the Cretaceous period, the paleo-latitude of the area was at 22. 4 - 23. 6°N.Therefore, a variation curve of paleo-latitude is established in this paper for the Guizhou terrainfrom Late Devonian to Late Cretaceous time.
