摘　　要：在小秦岭金矿田内,断裂构造控制着金矿床的产出,断裂带产状形态的变化、展布规律控制了矿体的形态、产状和富集规律,总结出缓—中等倾斜的矿脉沿断裂带走向和倾向普遍存在矿化强弱相间分布的特点。通过S505号矿脉1500m中段以上断裂构造对金矿体的控制条件及控矿规律研究认为,S505号矿脉严格受构造控制,并成功地预测了深部第二矿化富集段应在1000m以下。The fault structures control the occurrence of gold deposit. The ieatures, attitude and enrichment of ore bodies are controlled by the change of attitude and extension of fault belts. And there is a general feature that the ore beds, which are generally small or middling gradient and whose strike and dip are along the fault belt, distribute alternately following the maturity of mineralization. By studying the ore-controlling conditions and rules of the fault structure of No. S505 vein above the 1 500m midsection, it is revealed that No. S505 vein is strictly controlled by geological structures. And the second mineralization enrichment section in deep is successfully forecast under 1 000m.
