通过对东秦岭金堆城钼矿集区及邻区已有重、磁测量资料系统整理和研究，并结合地质、钻井等前人研究成果，对研究区的重、磁资料进行了处理，推断了研究区的断裂构造，分析了重、磁局部异常与已知钼矿点的分布特征，进而探讨了研究区的成矿有利区。研究结果表明，研究区主要断裂可以分为近东西向、北东向和北西向3组，近东西向和北东向两组断裂构造的交切点控制了岩浆岩体的空间侵位，并且控制了研究区钼矿点（床）的产出位置；钼矿（床）点分布在重力低异常区、重力局部低异常向高异常过渡的舌状伸出部位和化极后局部正负磁异常的边界上，并且与负磁异常相关；根据地质构造和已知钼矿点在局部重、磁异常中的反映，结合化探异常和断裂控矿特点，圈定了4个找矿有利区。

In this paper, the authors systematically studied the gravity and magnetic data obtained from the study area in combination with geology and drilling results. Gravity and magnetic field was processed, fault structures was inferred, the distributional features of residual gravity and magnetic anomalies with ore spots were analyzed, and the favorable areas for Mo prospecting was discussed. The re?sults show that the main faults of the study area can be divided into 3 groups: nearly EW?trending faults, NE-trending faults and NW?trending faults. The intersectional points of the EW?trending fault with the NE?trending fault not only controlled the emplacement space of the magmatites but also governed the location of the Mo?bearing bed. Mo?bearing beds are distributed in low gravity anomaly, the tongue?shaped part where low residual gravity anomalies grade into high residual gravity anomalies, and the boundaries of the positive and negative aeromagnetic anomalies, associated with negative magnetic anomalies in the study area. Based on geological structure and the features of residual gravity and magnetic anomalies with ore spots, combined with geochemical anomalies and features of ore?control?ling fractures, the authors delineated four favorable ore?prospecting areas.
