| Abstract: | We summed up methods of calculation of free-air gravity anomaly and Bouguer gravity anomaly,and calculated these two gravity anomaly with terrain correction in Central Andes arear.Bouguer gravity anomaly in area of higher orthometric height is often negative and similar to contours map of same area.Terrain correction is much less than free-air and Bouguer gravity anomaly,so it need not to be considered in the simple Bouguer gravity anomaly. |
