According to the Normalized Differential and the Theta map fracture identification techniques��this article fixes the locations of the Da Hinggan mountains fracture zone and the Heihe - - Qiqihar - - Baicheng fracture�� It verifies the existence of the Heihe - -Qiqihar - -Baicheng fracture�� According to previous research results as well as related geological and geophysical data��we argue that the Heihe- - Qiqihar- - Baicheng fracture is the tectonic bounda- ry of Erguna- - Xing'an plot and Songnen massif�� While the Da Hinggan mountains fracture zone is a giant deep fault which is attributed to crustal tectonic movements squeezed by weak structures of the Erguna - - Xing'an plot�� Utilizing Oasis Montaj gravity and magnetic inversion software for human- computer interaction��we conclude a reasonable ge- ological structure model suitable for the research area��
