Abstract: The distribution of gold deposits in Jiaodong peninsula, the most important gold concentration area of China, is strictly controlled by NE-NNE-trending faults.However, no large-scale gold deposits have been found under the Cenozoic rocks in Zhaoyuan-Daotouzhen section in the middle part of the fault zone.On the basis of summarizing the difference of metallogenic model and ore-controlling geological body in Zhaoping fault zone, the Bouguer gravity anomaly characteristics of 1:600 and 1:200 thousand scale are compared from regional and fault scale, and the distribution of regional structure and rock mass are clarified.Furthermore, the distribution of concealed ore-controlled geological bodies is revealed by 1:10000 high-precision magnetic survey and 1:10000 controlled-source audio magnetotelluric survey of representative section in the Banbidian area.The regional Bouguer gravity anomaly reveals the tectonic zone characterized by the relatively low density positive value((0~6)×10^-5 m/s²)near EW direction, the Linglong biotite granite characterized by the positive agglomerate density value(>2×10^-5 m/s²)and the Zhaoping fault characterized by the NE-NNE density step zone.The spatial distribution characteristics of the three groups of ore-bearing geological bodies show that the southern boundary of Linglong biotite granite is bounded by the EW-trending tectonic belt, and Zhaoping fault belt cuts through the early Linglong biotite granite.High precision magnetic measurements show that, ①Linglong biotite granite is cut by Zhaoping fault zone; ②The granodiorite with low density and high magnetism near EW-trending(relative magnetic field value is more than 100 nT)is controlled by the EW direction deep structural belt in depth; ③The series of granites within Zhaoping secondary fault(formed after the main mineralization period)of the ore deposit scale are characterized by NE-trending bead-like low density and high magnetic anomaly(relative magnetic field value over 40 nT).Both CSAMT sounding and boreholes in the middle of the survey area confirm that the buried depth of the granite dyke decreases gradually from south to north(towards the direction of the main fault).Therefore, the NE-trending Zhaoping fault belt and the nearly EW-trending tectonic zone jointly control the distribution of the rock mass, and the intersection of them is a favorable space for the production of gold orebodies, while the intruding granitic body itself is depleted in gold.The concealed gold deposits in Banbidian area were formed later than the main metallogenic period of Zhaoping fault.The result shows that the prospecting prospect of gold ore in the low-density zone near EW-trending is not optimistic.
