摘要
On the basis of lateral correlation of sedimentary facies in Caledonian strata on both sides of Jiangshan-Shaoxing fault, the distributions of moraine conglomerate and granites in Sizhoushan, Guiyang and Songshan,Fenyi were studied, and the tectonic attribute of South China Caledonian was discussed. The results indicate that there is no discontinuity of facies in Caledonian strata across the fault zone, but interdigitation of facies in the Nanhua-Cambrian system, and conformity of facies in the Lower Ordovician. The sources of Yangtze Block and Cathaysia Block are linked and there is no ocean between the two Blocks, evidenced by the finding of distal turbidites interbed within marine moraines developed on Yangtze Block and marine moraines interbed within thick turbidites on Cathaysia Block. South China Basin is not an original ocean, but a rift trough with transitional crust as basement, developed through finite extension on continental crust basement.
