中文摘要: 简要叙述冈瓦纳超大陆聚合过程和中非造山带泛非期地质构造过程,剖析了西冈瓦纳喀麦隆北部和乍得西南地区岩石构造单元及其形成的构造背景并对喀麦隆北部河流冲积物进行了重矿物分析。分析结果表明重矿物可能来自近源基岩,为西喀麦隆地体(Western Cameroon Domain)内的雷博巴(Rey Bouba)绿岩带和马约科比(Mayo Kebbi)弧岩浆岩带;重矿物中的自然金可能主要来自雷博巴绿岩带。分析结果为该地区砂金矿开采提供了一定的指示。
Abstract:The assembly of Gondwanaland and Pan-African orogeny were briefly presented. Then, the lithological units and their tectonic settings in the northern Cameroon and southwestern Chad were dissected based on previous research. On this basis, heavy mineral analysis was carried out for river alluvium collected from northern Cameroon. The analysis results (species and contents of heavy mineral) were consistent with the basement rocks of the Mayo Kebbi magmatic arc belt and the Rey Bouba greenstone belt from Western Cameroon Domain (WCD). Gold in the alluvium may come from Rey Bouba greenstone belt, and the analysis results may give a prospect for alluvial gold exploit in northern Cameroon.
