| 中文摘要: |
| 赞比亚卡伦比拉铜矿区位于世界第三大铜矿带卢弗里安弧形褶皱带西南端, 卡播姆波基底穹隆的东南缘,矿化分布在新元古界加丹加群木瓦夏组含火山碎屑物质的碳质千枚岩中。该铜矿区包括3个矿床:哨惕奴、恩特普赖斯、勇转皮特,其中哨惕奴矿床是卡伦比拉矿区中地质调查最详细的矿床,它包含两个矿体:Ⅰ#矿体长5500余米,宽500余米,平均厚度9.95m,平均品位0.71％；Ⅱ#矿体推断长度1200 m,宽500余米,平均厚度7.93 m,平均品位1.03％。通过对区域地质背景、矿床地质特征分析,认为该区矿床成因类型为沉积-成岩型铜矿床。 |
| 英文摘要: |
| The Kalumbila Copper field in Zamia is located at southwest end of Lufilian arc fold belt which is the third-largest copper belt of world. Geologically, it is also located on the southeastern margin of the Kabompo dome. The copper mineralization is hosted almost entirely within the Muwaxia group carbonaceous shale of Neoproterozoic Katanga formation, which contains volcano clastic materials. Kalumbila Copper field contains three major copper deposits, such as Sentinel, Enterprise and Intrepid. Sentinel deposit is the most advanced one in Kalumbila Copper field, has two ore bodies. The No.1 ore body is more than 5500 meters long, 500 meters wide, with average thickness 9.95 meters and average grade 0.71%; the No.2 ore body is about 1200 meters in length and 500 meters in width, with average thickness 7.93 meters and average grade 1.03%. Through analysis on the regional geological background and ore deposit geological characteristics, the paper concluded that the copper deposit is a sedimenta-diagenesis deposit. |
