招平断裂带大尹格庄矿区三维地质结构及断裂控矿规律

Three Dimensional Geological Characteristics and Fault Controlling Laws in Dayin'gezhuang Gold Deposit in Zhaoping Fault Belt

本文基于大尹格庄矿区264个钻孔资料,建立了矿区三维精细化地质模型,剖析了金矿床三维空间结构,指出了沿断裂构造深部找矿重点地段。三维可视化展现研究区浅部较为零散的矿体在深部连为一体,构成资源量超过200 t的超大型金矿床。对主要矿体开展品位、厚度及断裂构造形态变化的耦合关系表明,矿体存在沿走向、倾向等间距分布、侧伏和斜列分布规律,矿体富集区主要位于断裂沿倾向陡缓交替地段,进一步理清了断裂与金矿的耦合关系,显示了三维模型在深部找矿中的预测作用。

Based on 264 borehole data of Danyin'gezhuang gold deposit,3D refined geological model of this mining area has been established,three dimensional spatial structures of gold deposits have been analyzed,and key ore-prospecting sections along the ore-controlling faults have been pointed out.As showed by 3D visualization analysis,main ore bodies of the study area scattersd in shallow areas are connected to the deep,and make up a super big gold deposit witn a gold resource of.more than 200t.The coupling relationship between the grade and thickness of main ore bodies and the structures characteristics show that the distribution of ore bodies are equally spaced,laterally and diagonally along strike and dip.The gold ore bodies are easy to be concentrated in the areas wtih large structure slope changes along dip.The coupling relationship between fault and gold deposit has been further clarified.It demonstrates the predictive role of 3D model in the deep exploration of gold deposit.
