摘要
介绍了对地球构造格局、运动方式及其动力源问题研究取得的新成果。它不同于流行已久的以地球自转轴旋转和以软流圈带动岩石圈漂移以及随机的地幔柱(流)为构造动力源的观点,而是与黄赤交角(ε)相关的沿公转轴方向的统一应力场。认为中国西部NWW向压性、NEE与NNW向两组共轭扭(压)性及NNE向张性带交接,为来自全球SSW主压应力场形成的四组三维构造系,在全国、全球有广泛的分布。地球、火星为SSW应力场,为太阳系各星球有以各自综合力体现的黄赤交角(ε)相关的沿公转轴方向形成的统一应力场。经对地球有关规律及其各学说的系统研究,结合天文地质新进展及新星云说,将它们求同存异和有内在联系地统一到公转轴应力场格局中来,提出应力场星球说。为地球科学研究提供了一条新思路,并具理论。
The four tridimensional tectonic systems composed of NWW trending compressive fractures, NNE trending (shear) tensile fractures, NEE trending sinistral and NNW trending dextral conjugate shear (compressive) fractures on the earth are formed in the global SSW unified compressive stress field through studying the relationship of the integrated force produced by the oblique rotation of the earth and the obliquity of the ecliptic to the stress field. The principal compressive stress is of the oblique cyclic tectonic force along the pole of the ecliptic of the earth produced when the earth revolves round the sun with the obliquity ε of the ecliptic. The source of this force consists of such resultant internal and external forces acting on the earth as attraction oblique rotation force, gravitational equilibrium and differentiation and geocelestial physical force. The model of tridimensional fracture systems in the SSW stress field has been constructed and the star (nebular) hypothesis of the stress field developed and an outline of the dynamic system on the basis of the macroscopic analysis put forward. Through a comparison among various celestial bodies, the direction of the stress field of a celestial body is consistent with or equal to that of the pole of the ecliptic of the celestial body in its rotation. As soon as a celestial bodies formed a orbicule its stress field produced and brought about its development and evolution. As exemplified by the hypotheses of plate tectonics theory et al, a systematic comparison is made on the various laws concerning the earth discovered by many scientists in China and other countries and on various hypotheses of tectonics developed by them. Through assimilation and extension of these hypotheses and seeking the common ground while reserving differences, the author tries to incorporate the regularities of their generation, development and evolution that have organic and internal connection into the framework of four tridimensional fracture systems in the global SSW unified stress field. Thus a new explanation is made for them, and thus their contradictions are solved and they become harmonious. Therefore, in this sense the new hypothesis supplements, perfects and develops various features and laws discovered on the earth and their related hypothesis and furnishes a new idea for earth sciences. So it will also arouse the interest of the broad masses of earth scientists. This new hypothesis not only has geological and astronomical significance but also practical significance in hydrogeological, engineering geological, seismic and volcanic studies and hazard prevention and is of reference value for the study of geosciences related.
