摘要
With the help of regional magnetic data, the basement uplift and the top-and-bottom depths of the interfaces of the regional magnetic formations can be obtained. The study shows that when calculating the geological body with depth of h, the window size of the magnetic force should be 4～6 times of the depth, the scope of the matched frequency bands can be chosen and determined by the experiment. The horizontal size of the geological body has little effects on the calculation results. On the contrary, the buried depth of the top of the geological body, its thickness and the corresponding extent between the windows and geological bodies have played main roles.
