In order to resolve the elaborate explanation problem of geologic structure using the data of gravity and magnetic field,the paper proposes a method of tree-directional small subdomain filtering based on DCT.We analyze the offset technique,in which the phase of gravity anomalies of vertical dike is displaced by π/2,and deduce theoretical formulas,in which the planar gravity anomalies characterizing a vertical dike are highlighted using the DCT method to make their phases transform π/2.It is shown in model experiments that the planar location of the greatest gradient of the displacement result after coordinate transformation is the same as the projective location of the vertical step.Using the conventional method of small subdomain filtering to check gravity gradient zones in offset processing results of each direction and to stand out boundary characteristic of three directional anomalies,so the numerical calculation of three-directional small subdomain filtering can be achieved.In the application,the conventional small subdomain filtering can only discern 11 fractures,but the three-directional samall subdonmain filtering discerns 33 fractures in Hulin basin of Heilongjiang.It is shown that the technique of three-directional small subdonmain filtering can identify more information for horizontal location of planar fault structures.
