Abstract: Taking the Benxi-Linjiang area for example, the interpretation of aeromagnetic, gravity and electrical profiling data can provide geophysical basis for the inference of strata, structures, rock mass and orebodies of deep geology. The geological maps and sections are drawn to establish the three-dimensional geological model. By geophysical information processing, with analysis on the metallogenic mechanism of the Anshan-type iron deposit, several potential deposits are discovered in the exploration area.
