地球旋转轴变位所产生的作用力叫轴变力。该力控制着全球的地形地貌特征和构造运动特征。控制着近代海洋地质构造的发育特征。海岭走向与轴变主张应方向垂直时,其生长速度最快,斜交时较慢,平行时不生长,大多数转换断层的错动方向与轴变应力所要求的方相相一致, 轴变力的方向随着地史时期轴变方向变化而变化,所以地史时期大地构造线方向也变化,前震旦纪主要构造线的方向为近东西向,震旦纪到下古生代的构造线方向为近南北向。在轴变力作用下,古生代时期古大西洋和古乌拉尔海洋关闭,形成了阿巴拉契亚山脉、苏格兰山脉和乌拉尔山脉;中生代以来,则造成了岗互纳古陆的分裂和喜马拉雅山脉,岗底斯山脉的形成。 轴变力还控制了全球的地震分布与活动规律,控制了全球地史时期的内、外生矿床成矿地质条件及其矿床分布规律。
Earth’s rotating shaft displacement caused by the role of the shaft called shaft force. This force controls the global topography and tectonic movement features. Control the developmental features of modern marine geological structure. Ridge direction and shaft change proposition should be vertical direction, the fastest growth, slow ramp when parallel, does not grow parallel, the direction of the majority of the fault movement and axial deformation of shaft deformation required by the phase consistent with the axis change The direction of the force changes with the change of the axial direction during the geodesy period. Therefore, the direction of the geotectonic line in the geodesy period also changes. The direction of the main tectonic line of the former Sinian is near east-west and the direction of the tectonic line from Sinian to the Lower Paleozoic is near North-south. Under axial deformation, the Paleozoic Paleozoic and paleo-Urals closed, forming the Appalachian Mountains, the Scottish Mountains and the Ural Mountains. Since the Mesozoic, the fragmentation of the Holocene and the Himalayas, Formation of the Seychelles. Shaft deformation forces also control the distribution and activity of earthquakes around the world and control the ore-forming geological conditions of the exo-exogenous deposits and the distribution of their deposits in the global geo-history.
