| Pre-Sinian Basic Tectonic Framework of Northern South China and Its Evolution |
| Pre-Sinian Paleoproterozoic material records available in northern South China suggest that the Yangtze plate had been prololly connected with cathaysia there at that time.The terminal Paleoproterozoic Lüliang movement was a prelude to tectonic movement in South China.This movement gave rise to paleo-islands represented by the Longquan paleo-island in Zhejiang and Xinzi paleo-island in Jiangxi,which were later overlain unconformably by Mesoproterozoic sediments.Geological and paleomagnetic evidence indicates that South China broke up into the Yangtze plate and Cathaysian plate in or before the middle-late Mesoproterozoic.The two plates have characteristics of different styles of movement.During 1 100 to 800 Ma,amalgamation and collision between the Cathaysian plate and Yangtze plate were completed.The Jinning movement,which is considered to be equivalent to the Greenville orogeny,marks the end of the evolution of the pre-Sinian basic tectonic framework of South China. |
