The northern margin of Yangtze Block borders on Qinling orogen.In Changxing Phase, its rock-stratigraphic unit includes Changxing Formation and Dalong Formation. Changxing Formation is composed of carbonate sediment and its main sedimentary facies include platform facies, platform edge reef and bank facies, and platform edge’s slope facies. The result shows that the range of deeper basin is from west to east, i.e., from the western Guangyuan to Wangchang to Nanjiang to the western Hubei Province. And the deeper basin separated the Yangtze Block from the North China Block. This kind of pattern implies the direction of exploration and may indicate that the Yangtze Block and the North China Block have already joined as a whole land block before the Changxing Phase.
