通过近几年大梁金矿的勘查实践,在SⅠ、SⅢ矿化蚀变带共发现金矿体14条。为了总结勘查经验,进一步指导该类型矿床的发现,本文初步提出大梁金矿的磁法、连续电导率、瞬变电磁法、地质勘查模型:连续电导率模型中-高电阻率对应SⅠ矿化蚀变带金矿体的产出部位,高、低阻接触带以及中低阻异常内局部高磁异常地段为铅锌矿体赋存有利部位;瞬变电磁法显示中电阻率内串珠状低阻异常,见矿效果良好;北北西向大梁-双尖山复式褶皱及剪切带控制着大梁金矿4条矿化蚀变带的产出。
Through the exploration practice of GOLD gold mine in recent years, a total of 14 gold ore bodies have been discovered in SⅠ and SⅢ mineralized alteration zones. In order to summarize the exploration experience and further guide the discovery of this type of deposit, this paper initially proposed the magnetic method, continuous conductivity, transient electromagnetic method and geological prospecting model of the girder gold deposit. In the continuous conductivity model, the high resistivity corresponds to SⅠ mineralization The production sites of the variable gold ore bodies, the high and low resistive contact zones, and the local high magnetic anomalies within the medium and low resistivity anomalies occupy the favorable sites for the lead-zinc ore bodies. The transient electromagnetic method shows that the middle resistivity of the gold-bearing bezels is low Anomalies, see the ore effect is good; northwestern girder - double dip Shan fold fold and shear belt control gold ore belt 4 mineralized alteration zone output.
