Remote Sensing images can reflect figure features and spreading regularities of many geological factors intuitively，and display concealed structures and movable structures effectively. This paper describes the general tectonic structure of Ordos and the tectonic setting of Hangjinqi and interprets the RS images of Hangjinqi with the aid of information extracted by such means as texture analysis and fusion. Based on characteristics of such factors as hydrographic nets，tones，textures，and geomorphic and lithologic elements，the authors consider that there exist two conjugated fractures and two circular faults as well as another set of NNW-trending fractures in Hangjinqi. These fractures interlace with each other and form a special tectonic system favorable for mineralization. These structures resulted from the compression by joint tectonic stress from south and north.
