A tentative Apparent Polar Wander (APW) path for the Shan-Thai-Malay Block (STMB), SW Yunnan, China, is constructed based on the paleomagnetic results from the Upper Devonian (D=201.9°, I=31.3°, des=13.3°, k=5.7, N=25 samples, Plong=245.1°E, Plat=41.8°N), Lower Permian (D=247.0°, I=46.0°, a95=10.0°, k=8.5, N=28 samples, Plong=223.7°E, Plato6.8°N), and Middle Triassic (D=96.0°, I=-28.9°, a95=10.2°, k=8.1, N=28 samples, Plong=200.8°E, Plat=11.7°N), as well as the Upper Silurian published earlier. These results were isolated from high temperature components and passed fold tests. The APW path for the STMB resembles neither that of the Yangtze nor the North China blocks. However, the change of paleolatitudes of the STMB could be correlated with that of Australia, implying that they might be closely spatially welded during the Paleozoic, as suggested by geological evidence.
