山东大庄子金矿床地质特征及找矿预测

大庄子金矿床位于胶莱盆地与胶北地体接触带北缘,矿石主要为含金蚀变岩型和含金石英脉型两种。随着胶东地区矿床研究的发展以及大庄子金矿资源的不断减少,有必要对大庄子金矿进行成矿远景分析和找矿预测。通过对大庄子金矿矿体地质特征、已知矿体矿石品位及矿体厚度变化趋势的综合分析,获知大庄子金矿还具有可观的资源潜力,依据资源潜力可划分为个预测靶区,分别为已知矿体北侧的浅部和深部、已知矿体的深部和已知矿体南侧的深部。其中已知矿体北侧的浅部和深部找矿前景最好,也是最可能实现找矿突破的靶区,而已知矿体深部和南侧的深部次之;除此之外,已知矿体南侧的浅部也不容忽视。

广西乐业县岩旦—岩堂金矿床找矿模型及成矿预测

广西乐业县岩旦—岩堂金矿是滇黔桂"金三角"新发现的一处大型卡林型金矿,为探究该矿床深部及外围找矿潜力,明确下一步找矿方向,开展了详细的矿床地质特征研究,并结合土壤地球化学和地球物理勘探异常,建立了该矿床的找矿模型,从而对深部成矿进行预测。研究表明:矿床中分布的矿体主要为受断层破碎带控制的脉状矿体,其次为受地层控制的层状和似层状矿体;背斜核部的NEE向断层F_1是主要的控矿构造,矿体有沿断层向东侧伏的趋势;土壤地球化学异常以Au-As为主,沿断层分布,且断层东部地表以As异常为主,具矿体前缘晕特征;地球物理激电测深表明金矿体具有低阻高极化的特点,在断层东部的高极化异常明显增强,暗示存在隐伏金矿体。综合地质与物化探研究成果认为,沿NEE向F_1断层及其与近SN向断层的交会处具有较好的找矿潜力,为优先找矿靶区。
