中文摘要: 刚果(金)SICOMINES铜钴矿处于非洲著名的赞比亚-刚果(金)铜钴成矿带西端,是一个铜金属量达千万吨的特大型铜钴矿床。本文通过对该矿床地质特征和成矿规律的研究,认为该矿床为沉积-改造型层状矿床。成矿过程经历了新元古代早期成岩阶段的初始成矿期、成岩阶段的主成矿期、晚期Lufilian(卢菲利)造山运动及热液改造期和表生富集期四个阶段。该区Katanga(加丹加)系Roan(罗安)群R2(矿山)组地层为主要控矿层位。造山运动过程中的构造活动和变质作用,为成矿元素的重新活化、迁移以及富集提供了热液和物理化学条件;成矿后的新构造运动及区域性隆起抬升,为铜钴矿石的次生富集提供了前提条件。各期次构造活动共同影响,控制着矿体的产出形态、规模与产状。
Abstract:Congo (DRC) SICOMINES copper-cobalt mine locate in the western end of Africa Zambia - Congo (DRC) copper (cobalt) mineralization.,that copper metal capacity is about 10 million tons of extra large copper and cobalt deposits. Through the study of geological features and metallogenic regularity, that the type of deposit is a deposition - transformation of layered deposit. Ore-forming process has gone through the initial mineralization of Neoproterozoic early stage of diagenesis, the main mineralization of diagenetic stage, orogeny late Lufilian and the hydrothermal transformation of and supergene enrichment of four stages. The Roan R2 (mine) group of district Katanga is main ore controlling seam. Tectonic activity and metamorphism during orogeny, porvided the ore-forming elements of the re-activation, migration and enrichment of hydrothermal and physical and chemical conditions; Several tectonic activity and regional uplift after mineralization, provided the preconditions for the secondary enrichment of copper and cobalt ore. Phases of tectonic activity combined effect of the control the orebody output shape, size and occurrence.
