| A DISCUSSION ON THE MECHANISM OF FORMATION OF LATITUDINAL TECTONIC BELTS AND RELATED PROBLEMS |
| Prof. Li Sze-Kuang (J. S. Lee) had suggested that the change of velocity of the earth s rotation is the fundamental cause of crustal mo-vement and that tectonic systems are formed during the period of the spee-ding up of earth s rotation. We have calculated the stress distribution arisingfrom the change of angular velocity of earth s rotation assuming a simplifiedearth model which has three homogeneous spherical elastic layers corresponding to the liquid core and solid mantle and crust of the earth respectively and a boundary condition between the outer and the intermediate layer that the radial displacement and normal stress are continuous while the tangential displacement may occur frictionlessly simulating the effect of the low viscocity layer during long term motion. |
