Abstract

Simao basin iocates in East part of Paieo-Tethys tectonic zone. To its west is Lancangjiang orogenic beit and east is Aiiao-shan orogenic beit. Based on the iate Paieozoic foid basement,Simao Triassic sedimentary basin formed in the eariy continentai-isiand arc coiiiusion stage after the ciose of Paieo-Tethys ocean. Lots of viewpoints have been given to interpret its property,such as rear-iand basin,”deiayed”back-arc basin,rift basin and foreiand basin. In this paper,the authors argue,on the basis of the study of the texture,property,stacking pattern,the provenance（or paieo-current directions）of the deposits,the earth dynamics of the basin and the transfer mode of the basin center,that Simao Triassic basin was a rear-arc foreiand basin. Its deveiopment started before Anisian of Middie Triassic and controiied mainiy by Lancangjiang orogenic beit. In Late Triassic,effected by Aiiao-shan orogenic beit,the basin had the properties of compiex foreiand basin. At the end of Triassic,it transformed into an intracontinentai downwarped basin.
