Abstract: Daliuhang gold field is located in Qixia-Penglai gold belt, one of the three major metallogenic belts in Jiaodong gold concentration area.The study of metallogenic structure has always been the basis and premise of prospecting.Through the implementation of 8 wide area electromagnetic sounding profiles, one-dimensional inversion and horizontal derivative calculation, the deep geological structure and fault spatial distribution of Daliuhang gold field are inferred and explained, and the fault ore control law and prospecting direction are analyzed on this basis.On the apparent resistivity profile, there is a large area of low resistivity anomaly in the shallow, and the deep high resistivity anomaly is more obvious.The horizontal first-order derivative diagram shows that the NE-NNE zonal apparent resistivity anomaly is broken or twisted.The inferred interpretation shows that the shallow part of the study area is mainly Late Cretaceous granite, and the deep part is mainly Early Precambrian metamorphic basement rock series.The fault structures in the area are very developed.It is inferred that the slope angle of the tiger line fault interpreted is relatively steep, the extension depth of the South and North segments of the fault is about more than -2000 m, and the extension depth of the middle segment is at least -3000 m; The dip angles of the four main ore controlling faults in NNE trend are steep, and they are obviously slowed down at the elevation of about -600 m and -1600 m.the extension depth of the faults exceeds the elevation of -2000 m, and the deepest is more than -3000 m; Five NW trending post metallogenic faults are inferred, of which two are newly discovered faults.The comprehensive analysis shows that the ore controlling fault in the area is a secondary fault of the tiger line fault, and the former may be the ore guiding fault of gold mineralization; The depth range of 2000 ~ 3000 m of the four main ore controlling faults in the south of the study area, the deep dip wavy change position of the tiger line fault, and the small-scale faults and fissures parallel to and equidistant from the main ore controlling faults are the key directions for ore prospecting in the future.
