PLATE-TECTONIC SETTINGS OF THE DEVONIAN SEA BASIN OF GUANGXI

There have been different ideas about the nature of the plate teetonie settings of the late Paleozoic sedimentary basin in Guangxi: interare basin, marginal basin, back-are basin, passive continental-margin rift system and so on. On the basis of an integrated a-nalysis of previous data and by means of the methods for analysing sedimentary basins, the authors analyse the type of the basement, nature of sedimentary formations, tectonic positions, activity and style, magmatie activity and stratabound mineral, deposits of the Devonian sea basin of Guangxi. and consider that the plate tectonic settings of Guangxi during the Devonian were of the nature of divergent （or passive） continental margin.
