摘要
迪库卢希铜银矿床是刚果(金)卢菲利前陆的重要矿床之一。作者结合区域成矿背景,分析总结了矿区地层、构造、矿体和矿石特征及地球化学特征。该矿床的成矿过程分为4个阶段:早期成矿阶段、Cu-Pb-Zn-Fe成矿阶段、Cu-Ag成矿阶段、表生富集阶段。分析认为该矿床应为低温脉状热液型矿床,控矿因素主要体现在构造、成岩、岩性3个方面。加强对该矿床的研究将有利于指导卢菲利前陆的找矿方向。
The Dikulusi deposit is located in the Lufulian foreland of D.R.Congo,it’s one of the important copper-silver depos⁃its.Based on the regional metallogenic background,the characteristics of strata,structures,orebodies and ores,and geochemical char⁃acteristics are analyzed.The metallogenic process of the deposit can be divided into four stages:early metallogenic stage,Cu-Pb-Zn-Fe metallogenic stage,Cu-Ag metallogenic stage and supergene enrichment stage.Analysis shows that the deposit should be of low tem⁃perature vein hydrothermal type,and the ore controlling factors are mainly reflected in three aspects:structure,diagenesis and litholo⁃gy.To strengthen the study of the deposit will be helpful to guide the prospecting of the Lufulian foreland.
