| Abstract: | According to spherical harmonic coefficients of 360 orders of EGM96 Earth's gravity field model,density anomaly and tectonic stress in different depth of crust have been calculated.We can draw the following conclusions:1) In the area that there is large variation of density anomaly,tectonic stress is also have a large variation.Thus the density anomaly may be the main cause of tectonic movement;2) If density anomaly is constant,tectonic stress will increase with the increase of depth;3) The average tectonic... |
