Abstract: | By contrasting and analyzing the characteristics of gravity field nearby some important active faults in the continent of China, it can be found that the crust blocks where Bouguer anomalies are regionally positive (or relatively positive) are moving towards the terrestrial poles and the blocks where Bouguer anomalies in a tremendous area are negative (or relatively negative) are moving towards the equator. By analysis of mechanics and mathematics calculation and based on lots of practical data, the authors hold that the change in density of a crust block is a decisive factor that causes the horizontal movement of the continental crust, while magma activity is an important factor that leads to the change in density of a crust block. |
