摘要
采用基岩伽玛能谱测量方法详细研究了堡子湾金矿的成矿流体场特征 ,发现矿区内的矿化蚀变具有点状分布特点 ,是北东向和北西向构造交汇部位 ,不存在北东东向的矿化蚀变带 ,表明北东东向角砾岩带是成矿后的产物 ,矿床应为被改造的隐爆角砾岩型金矿 。
The metallogenic fluid field of the Puziwan gold deposit is studied by measuring the γ ray spectrometric density of subaerial rocks. It is discovered that the gold mineralization alteration appears in dot like pattern which is located at the intersection of NE and NW trending structures. The so called NEE striking metallogenic alteration zone does not found. It is deduced that the NEE striking breccia zone should be the result of post mineralization. The gold deposit should be classified as a reformed cryptoexplosive breccia type. The future prospecting strategy should be made accordingly.
