摘要
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3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。
Dazhuangzi gold deposit, which mainly includes gold-bearing altered rock type and gold-bearing quartz vein type, is located in the edge between Jiaolai basin and Jiaobei terrane. With the progress of research in Jiaodong and resource of Dazhuangzi gold deposit reducing, it requests analyzing on ore-forming potentiality and prospecting target. We can find that much resource can be found in surrounding and deepness of Dazhuangzi gold deposit by comprehensive analysis on its geological characteristics, ore-grade trend and ore-body trend. According to the resource potentiality it can be divided into three prospecting targets in Dazhuangzi gold deposit, they are lying on the north superficiality and deepness part of known ore-body which is the most importance one, the deepness part and the south deepness part of known ore-body which is the second importance one, meanwhile the superficiality part of known ore-body also need some farther exploration work.
