【摘要】 华南大陆形成于前震旦纪。元古代至中三叠世，华南属于华南—东南亚板块的一部分，泥盆纪以前是冈瓦纳古陆的成员；志留纪之后为太平洋古陆组成部分；晚三叠世以来属于欧亚板块，华南大地构造演化可分为扬子大陆裂陷（Ｐｔ—Ｓ）、江南地台（Ｄ—Ｔ＿２）和南华陆缘活动带（Ｔ＿３－Ｑ）三大阶段。扬子大阶段包括四堡阶段（Ｐｔ＿１＋２）、雪峰阶段（Ｐｔ＿３１）和华南阶段（Ｚ－Ｓ），三次大陆裂陷分别形成以四堡群俯冲杂岩为代表的四堡陆间沟一弧一盆、以丹洲群为代表的雪峰陆间沟一弧一盆和以震旦一志留纪广西构造层冒地槽型建造为代表的华南陆缘弧后盆地。江南大阶段含钦州、右江两个平行交错的局部阶段，钦州裂陷阶段（Ｚ—Ｐ＿１），位于华南陆缘弧后盆地局部钦州地区，并被保留至早二叠世；右江裂阶阶段（Ｔ＿１－Ｔ＿２），由于桂西及邻区介入活动大陆边缘，发育了右江裂陷盆地。南华大阶段包括两阶段，燕山期（Ｔ＿＃－Ｅ＿２￣２）东南大陆边缘弧阶段和南岭期（Ｅ＿２￣３－Ｑ）北西太平洋岛弧阶段。南华大阶段发生了多次轻缓造山运动，导致江南地台盖层和其上覆构造层同步或类同步褶皱，在陆上无海浸的环境里形成中新生代南华造山带。还讨论了许靖华关于华南三叠纪碰撞造山带的理论，结论?更多还原

【Abstract】 he continent of South China was formed in the Presinian Period. South China was one part ofthe South China-Southeast Asia plate from the Proterozoic Era to the Middle Triassic Epoch, anumber of Gondwana before the Devonian Period, a component of Pacifica after the Silurian Periodand a part of the Eurasinn Plate since the Late Triassic Epoch. The tectonic evolution of South Chinacan be divided into three megastages; Yangtze continental split-depressed （Pt-S） ,JiangnanPlatform （D-T₂） and Nanhua epicontinentai active belt （T₃-Q）. The Yangtze megastage includesthree stages : Sibao stage (Pt₁₊₂ ) , Xuefeng stage （Pt ） and South China stage （Z-S） , respectivelyforming the Sibao intercontinental trench-arc-basin represented by the subduction complex of theSibao Group , the Xuefeng intercontinental trench-arc-basin represented by the sueduction complex ofthe Xuefeng Group and the South China epicontinental back-arc basin represented by themiogecoyncline type formation of the Sinian-Silurian Guangxi structurai stuge. The Jiangnanplatform megastage contains two partial parailel interlaced stages : Qinzhou split-depressed stage andYoujiang split-depressed stage. The Qinzhou split-depressed stage（Z-P₁ ） was located in the Qinzhouarea of South China epicontinental beck-arc basin and lasted to Early Permian Epoch. In theYoujiang split-depressed stage（T₁-T₂） , the Youjiang split-depressed basin was developed owing tothe invofvement of West Guangxi and adjacent areas in active continental margin. The Nanhuamepemge includes two stages : Dongnan （ Southeast） continental margin stage of the Yanshanianperiod（T₃-E ） and Northwest Pacific island arc of the Nanling peried（E-Q） . Many gentle orogeniestook place in the Nanhua megastage, bringing about synchronous folding or parasynchronous foldingof the Jiangnan platform cover and its overlying structural stages, and forming the Meso-CenozoicNanhua orogenic belt in the terrestrial tectonic environment without sea ingression. Kenneth J.Hsu’s ideas about the Triassic collision orogens of South China is discussed. The conclusion isreached. （1 ） There was no paleozoic Hunan -Jiangxi-Zhejing ocean in the continent of South China;（2） No Triassic collision event between two continental blocks occurred in the continent of SouthChina. （ 3） The “Banxi” m’elanges are subordinated to the precise stratigraphical unit of theLengjiaxi Group and the Banxi Group as well as correeponding horizons restricteil by the Sibaounconformable tectonic interface and the Xuefeng unconformable tectonic interface.更多还原
