Paleomagnetic results from some Permian-Triassic rocks from southwestern China

The Ailao Shan fault zone in West Yunnan represents a suture boundary between South China and Indosinian Cratons. Preliminary paleomagnetic results from three sites in Sichuan, Guichou, and Yunnan Provinces reveal a 14° northward migration of South China Craton between Late Permian and Middle Triass...

Zusammenfassung:The Ailao Shan fault zone in West Yunnan represents a suture boundary between South China and Indosinian Cratons. Preliminary paleomagnetic results from three sites in Sichuan, Guichou, and Yunnan Provinces reveal a 14° northward migration of South China Craton between Late Permian and Middle Triassic. The two cratons were separated by about 20° latitudes during the Early Triassic. The tectonic setting of East Asia during the Triassic was probably analogous to the present Indonesian region.
