| 中文摘要: |
| 卢菲利安弧形构造带由泛非运动引起,该带由南往北可进一步划分为加丹加高地、复向斜带、穹隆区、外部褶皱逆冲带和前陆带等5个单元。泛非运动期间,卢菲利安弧经历了3个不同的构造变形阶段。文章对中非铜钴成矿带的地层层序进行了合理划分,将中非铜钴成矿带中的矿床类型划分为6种,最著名的为矿山亚群中的层状铜钴矿床,次为恩古巴群中以碳酸盐岩为容矿岩石的锌铅铜银矿床;总结了成矿带中矿床的时空分布规律,认为矿床受地层、岩性、构造和表生氧化作用的联合控制。 |
| 英文摘要: |
| The Lufilian arc is composed of Katagan High, synclinorial belt, domes region, outer fold and thrust belt and foreland from south to north, resulted from Pan-Africa orogeny, experienced three phases of structural deformation, including Kolwezian phase, Monwezi phase and Chilatembo phase. The stratigraphic sequences in the central Africa Cu-Co metallogenic belt are described. Six types of deposits are classified in the central Africa Cu-Co metallogenic belt. The stratiform Cu-Co deposits, hosted in the Mines Subgroup, are very famous. The carbonatie-hosted Zn-Pb-Cu-Ag deposits in the Nguba Group are also important. The temporal and spatial distribution of the deposits in the Cu-Co metallogenic belt is briefly summarized in the paper. These deposits in the Cu-Co metallogenic belt are controlled by stratigraphy, lithology, structure and supergene process. |
