| 中文摘要: |
| 在桂西北地区新发现了两个直接产于辉绿岩中、以辉绿岩为赋矿主岩的微细浸染型金矿床(点)。金矿床受断裂构造和岩性控制,含矿岩石为蚀变辉绿岩。矿区内基性岩为成矿提供了矿源和水源,并成为直接的赋矿主岩。找矿标志为:穿过辉绿岩的断裂蚀变带;发育硅化、黄铁矿化等蚀变作用;发育Au及Au、Sb、Hg、As元素综合异常。 |
| 英文摘要: |
| Two micro-disseminated gold deposits existed in diabase in Northwest Guangxi province were discovered, The deposits are controlled by faults structure and diabase, the later formed the host rock. The regional basic rocks have supplied resource material and water source.and acted as host rock. Ore-finding signals were surranaried as fellows:altered faults structure crossed the diabase; with alteration as silicefication and pyritization,and Au anormal,Au, Sb, Hg, As elments combined anomal. |
