东秦岭钼矿带是世界上重要的钼矿带之一，带内分布着几个超大型钼矿床，南泥湖钼矿床就是其中之一．南泥湖钼矿床含矿裂隙含脉率、含脉密度及含矿裂隙产状研究结果表明：１．钼矿化受裂隙和含脉率控制；２．南泥湖钼矿床含矿裂隙具有明显的方向性，走向主要为ＮＥ—ＮＮＥ向；３．含脉率越高含矿性越好，含矿裂隙的发育程度对蚀变岩分布范围和交代程度具有明显的影响．
The East Qinling molybdenum belt is one of the most important molybdenum ore belts in the world. There are several super-large molybdenum deposits in the belt. Nannihu molybdenum deposit is one of them. The results show that: 1. The results show that: 1. Molybdenum mineralization by cracks and pulse rate control; 2. The ore-bearing fissures in Nannihu molybdenum deposit have obvious directionality, and the main trend is NE-NNE direction.3. The higher the pulse rate is, the better the ore-bearing property is. The development degree of ore-bearing fractures has a significant effect on the distribution range and accountability of altered rock.
