摘要
阐述了老柞山金矿的成矿地质条件、矿体地质特征,总结了成矿规律。其中断裂构造的交汇部位是矿体产出的有利地段。具体的控矿地质因素为:矽卡岩因素、成矿阶段因素、矿物的组合因素、矿体侧伏规律等。根据上述规律对老柞山金矿的东采区进行了深部预测,将东采区划分为两个金矿体侧伏带,其中南侧金矿体群的侧伏特征指示了220m标高以下金矿体群有向下延伸的可能,北侧的金矿体群在140m标高向上和向下都有延伸的可能。
The ore-forming geological conditions, ore body geological characteristics and metallogenic regularities have been summed in this paper. The intersecting points of faults are important ore-forming sections. Some importa＇nt ore-controlling factors, such as skarn, ore-forming stages, mineral assemblage and ore body assemblage indicate the existence of mineralized sections. Based on the above law, the deep ore-forming predication has been made in the east mine area in Laozuoshan gold deposit. All The ore bodies in the east mine area can be divided into two ore body groups, pitch features hint that the ore bodies extending below 220m level and over or below 140m level for south side ore body group and the north side ore body group,
