| 文章以坦桑尼亚Shageige磁铁石英岩(BIF)型金矿预查区为研究对象,运用地质填图、地球物理、地球化学相结合的研究方法,系统研究了预查区内地层、构造、岩浆岩的分布和特征,对预查区内成矿有利构造及磁铁石英岩(BIF)与变凝灰岩接触带重点剖析,研究分析区内控矿构造及矿化蚀变特征,查明区内成矿地质特征及找矿标志；通过研究区内M1金矿体与剪切带空间结构的匹配关系,厘定了剪切带形变特征和发育阶段对金成矿的控制作用,并结合区内剪切带的矿化特征,总结了控矿规律和找矿潜力分析。 |
| 英文摘要: |
| In this paper,the geological mapping,geophysics and geochemistry are used to systematically study the distribution and characteristics of strata,structures and magmatic rocks in a magnet quartzite (BIF) type gold deposit preview area in Tanzania. The favorable metallogenic structures in the pre-exploration area and the contact zone between (BIF) and altered tuff are analyzed,and the ore-controlling structures and mineralization alteration characteristics in the area are studied and analyzed. To find out the metallogenic geological characteristics and prospecting criteria in the area; By studying the matching relationship between M1 gold orebody and spatial structure of shear zone,the deformation characteristics of shear zone and the control effect of development stage on gold mineralization are determined. Combined with the mineralization characteristics of shear zone in the area,the ore control law and prospecting potential analysis are summarized. |
