| 中文摘要:华南(北部)古元古代已有物质记录，且可能曾连于一体。古元古代末期吕梁造山运动揭开华南构造运动的序幕，形成以浙江龙泉、江西星子等为代表的古岛，并被随后的中元古代沉积物不整合所覆。地质学及古地磁学证据表明，中元古代中后期或之前其被裂解为扬子板块与华夏板块，各板块具有不同的运动特征。大致在1100一800Ma期间，华夏板块与扬子板块完成拼贴与碰撞，这一称之为与格林威尔相当的晋宁运动标志着华南前震旦纪演化的结束。 |

| Abstract: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. |
