The gravity anomaly of the southern part of the Gyeongsang basin and the adjacent sea is analyzed. According to the power spectrum analysis method, calculated the mean depth of the moho and the boundary between the sedimentary layer and the basements is 32㎞ and 61㎞ respectively. With these values, regional and residual anomalies of the gravity for each depth are calculated by the running average method and interpreted. By the sin X/X method, the crustal thickness and the depth of the boundary of the sedimentary layer in the southern part of the Gyeongsang basin turns out to vary from 34㎞ to 28㎞ and from 8.5㎞ to 0.5㎞ respectively.
