| 摘 要： | 通过地质构造、显微构造和构造地球化学特征分析，论述了辽西阜新金－多金属成矿区主要断裂带的构造特征及其控矿作用，并着重指出NEE向、NNE向韧－脆性剪切带是本区主要的控矿和导矿构造，而NEE向构造的NW向次级断裂带和NNE向构造的EW向次级断裂带则为本区主要的容矿构造，现已探明的金－多金属矿体也多沿这两个方向展布。

| Abstract: | The major fracture zones in the gold-polymetallic ore-forming area in Fuxin, Liaoning Province, were studied by analyzing macrostructural features, microstructural deformation and tectonogeochemistry. The basic features of these zones and their control over the ore-forming process are discussed in this paper. The authors point out that the NEE-and the NNE-trending ductile-brittle shear zones are the major structures serving as the controlling factor and the passageways for fluids in the gold-forming district of Fu-xin area, and that the NW-trending faults and the EW-trending faults, which are the second-order faults in the NEE-and the NNE-trending faults, are important host structures along which the present explored gold orebodies are distributed. |
