试论地幔潮汐作用与地壳构造运动的关系

太阳系（携带地球）围绕银河系银心依椭圆形轨道公转．旋行１周，地球与银心之间有两次处于近距离，两次处于远距离．在靠近时两者之间引力增大，导致地仅柔流物质发生涨潮，远离时引力减小，地幔潮落．地幔的潮汐作用势必引起其上的固体地壳发生破裂、变形、运移和碰撞，即地壳构造运动．由于太阳公转具有２００Ｍａ年的周期性，故而地壳运动同样也具有与此相一致的周期性和等时性．因而说地幔的潮汐是导致地壳发生构造运动的主要原因．

A TENTATIVE APPROACH TO THE RELATIONSHIP BETWEEN THE MANTLE TIDE AND TECTONIC MOVEMEMT OF THE CRUST

t is known that the solar system together with earth is revolving around the Galaxy in an orbit of elliptical form. In this way, there exist two times of nearest distance and two times of farthest one between earth and galactic center when the solar system moves in a circular course. The gravitational force between earth and galactic center is strengthened each time when each other close. Thus it results in rising tide of soft materials in mantle. Oil the contrary, when the gravitational force reduced, it leads to the ebb tide of soft materials in mantle. The ebb and flow of the tides of mantle is bound to result in fracturing,deformation, movement and collision of the solid crust, that is crustal movement. Owing to the revolution of solar system with a 200 Ma Periodicity, the crustal movement is consistent with that as well. So, the authors considered that the dynamics tectonic movement of the crust might be attributed to the bides of the mantle.
