| 摘 要： | 采用研究成矿地质作用确定成矿地质体、研究成矿构造分析矿体空间分布特征、研究成矿流体确定找矿方向的"三位一体"研究方法,对陕西汉阴坝王沟金矿进行找矿预测,认为矿区成矿地质体以大型脆-韧性剪切带变形构造为主;成矿构造为脆韧性剪切带转换带、叠加带;成矿结构面主要为S-C面理;成矿作用特征标志为黑云母变斑晶绢云石英片岩+变砂岩或硅质岩。利用找矿预测研究成果,在坝王沟金矿预测了有利成矿地段并提出勘查工作部署建议,找矿成果取得较大突破,表明"三位一体"找矿预测方法对开展矿产勘查工作有很强的指导意义。

| Abstract: | Using the trinity prospecting model which study the metallogenic geological processes to determine the metallogenic geological bodies, study the metallogenic structure to analyze the spatial distribution characteristics of ore bodies and study the ore forming fluid to determine the direction of ore prospecting, the prospecting forecast of the Bawanggou gold deposit in hanyin, shaanxi was researched. It is concluded that the large brittle ductile shear zone is the main deformation structure of the ore-forming geological body in the mining area. And the main metallogenic structures are the transition and the superimposed places of the ductile-brittle shear zone. The metallogenic structural plane is mainly the S-C foliation. The characteristic indication of mineralization is the formation of biotite phenocryst sericite quartz schist and sandstone or siliceous rocks. By using the prospecting prediction results, we predict the favorable metallogenic area and put forward suggestions for the exploration work in the Bawanggou gold deposit which is a major breakthrough in prospecting achievements. It indicates that the trinity prospecting model is of great guiding significance for the development of the mineral exploration work. |
