三大洋的洋裂谷都是经向系构造,其水平扩张运动,推挤陆壳作垂直隆升运动,并发展华夏等其他构造系。以此构造体系内的动力成生联系可推演到体系之间,并由洋、陆壳代表形成全球构造系统。这在我国西南地区这一小层次的奥陶纪地质演变中也得到了证明。并都表现出与热力学系统开放、封闭相对应的侵变,耗变周期发展过程,作者曾提出的海陆“抗建”可作为它们的统一动力模式。 The ocean rifts of the three oceans are all meridional structures that horizontally expand and push the continental crust for vertical uplift and develop other structural systems such as Huaxia. The dynamical connections within this structural system can be deduced into the system and represented by the oceanic and continental crust to form a global tectonic system. This is also evidenced by the small-scale evolution of the Ordovician in southwestern China. And all show the process of invading and consuming cycles corresponding to the opening and closing of the thermodynamic system. The “anti-construction” proposed by the authors in the past can be regarded as their unified dynamic mode.
