| 摘 要： | 讨论了一些有关地壳均衡概念的模型。业已证明 ,这些模型既不能用以正确评估地球的平衡状态 ,也不能用以解释构造成因。介绍一种新的地壳均衡模型 ,它与地球的某一种旋转方式相适应。地球体与球的偏差 ,被用来作为地球平衡的判据。地球被认为是在偏差趋近于零的那些点上得到平衡的。地球体与球体之间标志的差异 ,是由地球外壳中地质作用的方向所确定的。所提出的是大地地壳均衡模型 ,是地壳中构造形成新旋转假说的基础。

| Abstract: | Some classical models of isostasy are discussed. It has shown that they can be used neither for appreciation of equilibrium state of the earth, nor for the explanation of tectogenesis. A new model of isostasy is introduced corresponding to a certain rotational regime of the earth. As a criterion of the earth's equilibrium is taken the deviation of the geoid from the spheroid. The earth is considered to be balanced in points where this deviation is approaching to zero. The difference of the marks between the geoid and the spheroid is determined by the direction of geological processes in upper envelopes of the earth. The proposed model of geoisostasy is the base of the new rotational hypothesis of structure formation in the crust. |
