| 摘要: |
| 晚古生代-中三叠世,中国南方在陆块间离散-聚合的不同构造运动体制下,分别在扬子陆块内部和边缘形成了不同的盆地原型及其演化序列。在扬子陆块的西南缘,主要形成裂谷-被动大陆边缘坳陷-弧后盆地的原型演化序列;扬子陆块南缘发育裂谷到台内坳陷再到裂谷原型演化序列;扬子陆块内部主要形成台内拗陷-裂谷的原型演化序列。古特提斯洋演化对晚古生代构造和盆地原型的演化起决定性作用。 |

| Abstract: |
| The distinct basin prototypes and their evolutionary sequences were developed within or along the Yangtze landmass in the divergence-convergence tectonic regimes in southern China during the Late Palaeozoic to the Middle Triassic.The rift-passive continental marginal depression-backarc basin sequences occurred along the southwestern margin of the Yangtze landmass.The rift-intraplatform depression-rift sequences were developed along the southern margin of the landmass.The intraplatform depression-rift sequences were organized within the Yangtze landmass.The evolution of the Palaeo-Tethys may have exerted an important influence on the formation and evolution of the Late Palaeozoic tectonics and basin prototypes. |
| Key words: Late Palaeozoic southern China divergence-convergence basin prototypes |
