Abstract On the basis of calculating the fractal dimension of the aeromagnetic data from Bayan Hot basin, a fractal contour map was drawn and the distribution of igneous rocks was deduced according to the fractal characteristics. From the map, the relatively good geological result which cannot be obtained from the aeromagnetic contour map has been attained. In the end of this paper, the selection of the optimal window and the optimal grid for calculating fractal dimension is discussed, and some experience is advanced.
