摘　　要：陆院沟金矿床位于河南省洛宁县熊耳山金、银多金属矿集区。矿区内矿脉主要受近南倾的层间破碎带控制,其中3;矿脉局部发育富矿包,存在于北东倾节理和层间破碎带交会部位。结合野外勘查,对富矿包的成因和成矿规律进行了系统分析和归纳总结,提出富矿包分布在凝灰岩层上盘、南东侧伏、间隔150~200 m尖灭再现等认识。根据以上认识,针对富矿包进行了成矿预测,并得到工程初步验证。Luyuangou Gold Deposit is located in Luoning County, Henan Province, and affiliated to the Xiong’ershan gold, silver and polymetallic high ore concentration area.The ore veins in the mining area are mainly controlled by the near-south dipping interlayered fractures.Among them, locally in 3;ore vein develop ore-rich knots, which occur in the intersection of the NE-trending joints and the interlayer fractures.Based on field investigation, systematic analysis and summary are carried out, proposing new ideas such as distribution of the ore-rich knots on the upper part of the tuff layer, SE concealing, 150-200 m intermittent pinching-out and reappearance.Based on the above understanding, the genesis of the ore-rich knot is predicted and preliminarily verified by engineering.
