SPECULATIONS ON THE CRUSTAL TECTONIC EVOLUTION OF JIANGXI

This paper deals with the basic features of the pre-Caledonian, CaledonianIndosinian and Yanshanian crusal tectonic evolution of Jiangxi Province. The author considers that in the pre-Caledonian the crustal tectonic evolutions were different in the yangtze region, the Cathaysian region and the Hunan-Jiangxi-Guangdong region.
