摘要
基于大尹格庄金矿床大量探采资料的综合研究,通过深入剖析其构造系统的控矿规律,探讨了其找矿意义。大尹格庄金矿床控矿断裂构造分为三级,依次控制了矿床的总体展布,矿体的规模、形态和产状及矿化的局部富集。断裂带内构造变形强度和构造岩的类型及性质组合控制了矿化和蚀变的类型、强度及产出位置。NE和NNE向压扭-张扭性断裂构造,主次级断裂的分支复合,蚀变带中脆性断裂叠加发育,断裂带沿走向和倾向产状变化,主断裂旁侧次级断裂发育等均是有利的找矿构造标志。
Based on synthetic analyses of exploration and production data, significance of ore prospecting in the Dayingezhuang gold deposit is discussed through studying ore - controlling tectonic system. Ore - controlling structures can be divided into three classes, and successively control general distribution pattern, scale, shape, and occurrence of ore bodies and local mineralization. Combination of tectonic deformation and tectonic rocks in structural belts controls type, intensity and location of mineralization and alteration. The favorable tectonic ore prospecting marks are NE - and NEE - trending compresse - shear to tenso - shear structures, combination of major and secondary structures, well developed superimposing of brittle structures in alteration belts, structure occurrence changes along strike and dip, and well developed secondary structures near the main structures.
