中文摘要:
      为评价哈西哇金矿深部盲矿的找矿前景,为深部圈定找矿靶区,本文在研究矿床地球化学背景及矿床地质特征的基础上,对哈西哇金矿床进行了构造叠加晕的研究。通过对哈西哇金矿床1号矿体进行采样,并化验分析了所采样品中Au、Ag、As、Sb、Hg、B、Cu、Pb、Zn、Bi、Mo、Mn、Co、Ti、V、Ti、W、Sn等18种元素含量,研究了矿床元素组合和含矿构造中岩石地球化学异常在空间分布中所具有的特征。结果表明,哈西哇金矿床成矿作用伴随有微量元素富集,存在明显的原生晕轴向分带规律。根据构造叠加晕找矿预测指标,对1号矿体深部资源潜力进行了预测评价,提出一个预测靶区,为矿山的下一步勘探开发提供了理论依据。经钻孔ZK1603验证有良好的见矿效果,为矿区周边深部找矿提供参考意义。
英文摘要:
      In order to evaluate the prospecting potential in the deep of the blind orebody in Haxiwa gold mine area and delineate a deeper ore-finding target, the research of the structural superimposed halo of Haxiwa gold deposit was carried out on the basis of geochemical background and geological characteristics of the deposit. This paper, presents data for rock samples that were systematically collected during the exploration of the No. 1 gold-bearing quartz vein of the Haxiwa gold deposit, and 18 elements determined to investigate the geochemical characteristics of the deposit. The elemental combination of the deposit and the spatial distribution characteristics of the primary halo in the ore-control fault were systematically studied. The results show that the metallogenesis of Haxiwa gold deposit is accompanied by enrichment of trace elements, and there is obvious axial zoning of primary halo. Finally, according to the prediction indicators of the theory of structural superimposed halo, the potential resource of the deep part of the No.1 gold-bearing quartz vein is predicted and evaluated, and one prediction target are proposed, which provides a theoretical basis for the next exploration and development of the deposit.The prediction of the target area is good which is verified by ZK1605 borehole, it provides reference for deep prospecting around the mining area.
