摘要
对非洲中南部卢弗里安地区Cu-Co矿床的大量研究成果进行了总结,概括了典型矿床的区域地质背景、岩石地层划分,较为系统地分析了成矿带中矿床的地质特征和矿床成因。得到①罗安群成岩年龄为765~735Ma,这也是同生沉积层状铜钴矿的形成年龄;②后期多阶段改造的主要成矿年龄为510~500Ma,主要受到卢弗里安时期复杂的逆冲推覆断裂和褶皱控制。
The authors summarize previous research results of Lufulian area Cu-Co metallogenic belt in south-central Africa including its regional geological background, lithostratigraphic classification, and systematically analyzed the geological characteristics and deposit genesis. A lot of evidence support the following understanding on this ore deposit： 1） Roan Group diagenetic age is 765--735 Ma and this age also belongs to the formation age of syngenetic sedimentary bedded Cu-Co deposits; 2） the main mineralization age of the later multi phase transformations is 510--500 Ma and the main transformations were controlled by complex overthrust faults and folds of Lufilian period. The aim of the discussion in this paper is to supply important reference for deeper level study of this type of deposits and Chinese enterprises which will invest abroad.
