重力确实是断层斑图形成和岩石圈向西位移的driving force

Gravity is indeed the driving force for fault pattern formation and westward displacement of the lithosphere

Andres R. R. Papa

摘要:

太阳和月球对地球的引力影响是造成我们现在所观察到的地球表面断层图象的原因,也是岩石圈向西位移的原因。过去提出的一个有点相关的假设是,月球的潮汐扭矩可能很重要。然而,有人认为,这是站不住脚的基本理由是,地球地幔的粘度是远远高于所涉及的力量。为了说明这一点,假设地球的相关特性是由粘性液体分开的两个球壳,外壳相对于内壳以恒定的角速度旋转。在这里,我指出,这幅图并不完全正确,更仔细地观察,我们会发现,两个壳以不同的平均角速度旋转,并有一个前后相对运动的序列。这样,原本被认为是对抗重力影响的主要因素,变成了主要的有利因素。

英文摘要:

Gravity influence of the Sun and the Moon on the Earth is the cause of the fault pattern on Earth's surface we observe nowadays and also of the westward displacement of the lithosphere. A somewhat related hypotheses advanced in the past have been that tidal torque of the Moon may be significant. However, it has been argued that it is untenable essentially on the grounds that the viscosity of the Earth's mantle is far too high in comparison with the forces involved. To state this it was assumed that the Earth's relevant characteristic is that of two spherical shells separated by a viscous liquid, the external shell rotating at a constant angular velocity with respect to the inner shell. Here I show that this picture is not quite right and that a more careful look leads us to one in which both shells rotates at different mean angular velocities and with a forward-backward sequence of movements relative to each other. In this way what was supposed to be the principal factor against gravity influence becomes the main favourable one.
