Abstract: 1 228 geochemical samples were collected according to a certain grid in the surface of Dehelongwa mining district，and the content of 20 trace elements was analyzed，by the geochemical properties of each trance element and the co-relationship between each trance element and ore-forming elements，abnormal combinations of multiple geochemical elements were divided，and the abnormal geochemistry structure mode in this area was analyzed.The research shows that the abnormal geochemistry structure mode does consistent with actual situation in this area.There were three structural broken belt were developed in research area，the magmatic activities and forming of ore bodies were all controlled by this three structural broken belt.So the structural broken belts are the important areas for the further ore-prospecting work.

Key words: Coexistence combination of multiple chemical elements, Mode of abnormal geochemistry structure, Structural broken belt, Dehelongwa
