摘要
在曹家埠金矿床经过多年探采总结的地质编录基础上,简单介绍了曹家埠金矿区的矿床地质特征。从矿脉的空间分布,矿体形态、产状、规模,矿体与围岩的关系,矿石结构、构造,矿石类型,矿石的矿物成分和化学成分、变质作用和围岩蚀变、矿化阶段划分和矿床成因等方面综合论述了该矿床的地质特征,并对矿床成因进行了初步研究探讨。同时分析了矿体成矿规律与找矿标志,并重点论述了该区的控矿构造特征、赋矿规律。通过对曹家埠及其平里店周围的矿床、矿点多年的探采工作,对这类金矿床的控矿构造规律有了新认识,为矿区开展深部和外围探矿,提供了一套合理的找矿方法和理论。
Based on the geological logging summarized by many years' exploration of Caojiabu gold deposit,we introduce its geological characteristics simply. From the spatial distribution of ore vein, the form, occurrence and size of orebody, the relation of orebody to host rock, ore textures and structures, ore types, ore mineral and chemical composition, metamorphism and host rock alteration, mineralization stage and ore genesis, we make a comprehensive discussion of geological characteristics of the deposit, and preliminary study the genesis of the deposit. We analyze mineralization of the orebody and prospecting criteria at the same time, and focus on the characteristics of ore-controlling structure. After many years' exploration of Caojiabu deposit and its Pinglidian ore point, we have new recognization for ore-controlling structure regularies of this type gold deposit, also it provides a reasonable prospecting method and theory for prospecting in depth and external.
