The Star (Nebular) Hypothesis of the Stress Field $$$$ The Global SSW Stress Field and Tectonic Framework in China and Adjacent Regions

摘要

The four tridimensional fracture systems composed of WNW-trending compressive fractures, NNE-trending tensile(-shear) fractures and ENE-trending sinistral and NW-trending dextral conjugate shear(-compressive) fractures on the earth are formed in the global SSW unified principal compressive stress field. The direction of the principal compressive stress is that of the unidirectional vortex tectonic force formed in the direction of 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 is the integrated force of the resultant internal and external forces acting on the earth, such as gravitation, oblique rotation force, gravitational equilibrium and differentiation and geo-celestial physical forces. The model of the four tridimensional fracture systems in the SSW stress field has been constructed (Fig. 1) and the star (nebular) hypothesis of the stress field thus developed. In this paper, the control of the hypothesis on the tectonic framework of China and the adjacent regions in the SSW stress field is discussed briefly.
