由此可以清晰地看出，在古生代早期全球各大陆的主要部分都位于赤道附近及南半球，大致表现为沿纬度、呈东西向排列的特征，中国及邻区的小陆块群在古生代始终都处在劳伦大陆、西伯利亚与冈瓦纳大陆之间；随着西伯利亚大陆的快速北移，在劳伦大陆与冈瓦纳大陆的西部地区发生南北向拼合，亚皮特斯洋和里克洋的消亡，到古生代晚期形成统一的泛大陆；而冈瓦纳大陆的东部（澳大利亚和印度等）则逐渐向南移动、离散，地壳张开，构成古特提斯洋；中国及邻区的小陆块群则一直处在古特提斯洋中，保持离散状态，总体上缓慢地向北运移，并逐渐转为近南北向的排列方式，石炭纪到三叠纪才在天山兴安岭、昆仑山、秦岭大别、金沙江和绍兴十万大山等地段发生一系列局部性的陆陆碰撞，使中国大陆地块的大部分逐渐并入欧亚大陆。
