Abstract: There are three major fault blocks in China, i. e. the North China block province (consisting of six subblocks), the Yangtze block and the Tarim block. Their origin, development and consolidation are controlled by the pre-Sinian orogenies. One fault block may have been resulted from a single orogenic cycle or in most cases a few orogenic cycles because of the pre-Sinian orogeny was characterized by multiple cycles. Since the idea that an orogeny is occurred simultaneously all over the world was generally denied by most geologists, we consider that the orogeny must also be diachronous" especially in non-metamorphic sequences. Moreover, we suggest that the Jinning orogeny in the Yangtze block is a good example of such diachronous orogenies.But in the metamorphosed sequences, an uncomformity which can be observed in geological section may generally represent a combinative expression of many orogenies.Oro'genic cycles in these three major fault blocks have been classified as follows:Sanggan cycle (>2500-2600 m.y.)Wutai cycle (>2000 m.y.)Zhongyue cycle (>1700 m.y.)Yinshan cycle (>1200-1300 m.y.)Jinning cycle (>1050-900 m.y.)An attempt to correlate them with other orogenies that occurred in the other continents of the world is made in this paper.
