Abstract：Having interpreted some seismic sections which are calibrated with cropping materials and drilling data, we have found that under the Kumugeliemu anticline of fold overtbrust belt in Kucbe foreland area, there exists a very particular fault, which makes new and old formations be in apbroid to form aphroid structure style. Generation mechanism of apbroid structure is analysed by using tectonic theory of fold overtbrust belt, rock salt flowing mechanism and balanced section principle. A new method for plane correlating faults which are related to apbroid structure is described in this article.
