On basis of the three-dimensional geological survey completed in the Benxi-Linjiang area in eastern Liaoning-southern Jilin Province where the metamorphism and deformation are complicated, and by repeated practice and exploration, we conclude that subdivision three-dimensional geological survey method controlled by four-level profiles comprised of regional trunk profile, regional modeling profile, modeling constraint profile and modeling profile can constrain the deep geologic structure effectively. We also proposed 17 steps for conducting a three-dimensional geological survey and discussed the application situation, effectiveness, operability of this method and process and reliability of the result.
