摘要:

金青顶金矿床是牟乳金成矿带上唯一的特大型石英脉型金矿床,经过多年开采,其黄金储量已近枯竭。随着深度的增加,探矿增储难度越来越大,加强地质探矿科研工作、寻找第二富集带是摆脱资源危机的唯一选择。2008年,在前3次跟踪研究金青顶金矿床原生晕—构造叠加晕特征的基础上,开展第4次构造叠加晕研究,建立完善了金青顶金矿床深部盲矿预测的构造叠加晕模型,用模型不断向深部推进预测,并提出-1 000 m以下的成矿靶位,为深部地质探矿提供依据。目前,经验证取得了良好的找矿效果。

Abstract:

Jinqingding gold deposit is the only large quartz vein type gold deposit in Mouping-Rushan gold metallogenic belt.Though exploitation of many years,its gold reserves nearly exhausted.As the depth increasing,prospecting and increasing reserves are extremely difficult.Stengthen geological prospecting research and find out the second enrichment zone is the only option out of the crisis of resources.In 2008,base on the first three follow-up study characteristics of the original halo-structure superimposed halo in Jinqingding gold deposit,to carry out structural superimposed halo of the fourth,establishing and improving Jinqingding blind ore gold deposit structure superimposed halo model prediction,using the model forecasts continue to promote deep and made-1 000 m below the ore-forming target site,to provide the basis for deep geological prospecting.Now,proven to achieve a good deep exploration results.
