| 中文摘要: |
| 刚果(布)米拉铜矿为层状砂岩型铜矿,铜矿(化)主要产于Mpioka组下段(Pt3m1-1)顶部的青灰色、灰白色长石石英砂岩中,为氧化型铜矿床。主要矿石矿物有孔雀石、辉铜矿、自然铜、赤铜矿,次要矿物有磁铁矿(赤铁矿)、斑铜矿、蓝铜矿、铜蓝及黄铁矿等。成矿可分为原始沉积富集、构造热液改造富集、次生风化淋滤富集3个阶段。 |
| 英文摘要: |
| The Congo(Burundi) Mila copper mine is a layered sandstone copper mine, which is mainly produced in the gray-gray and gray-white feldspar quartz sandstone at the top of the lower section(Pt3m1-1) of the Mpioka Group and is an oxidized copper deposit.The main ore minerals are malachite, pyroxene, natural copper, hematite, minor minerals such as magnetite(hematite), spot copper, blue copper, copper blue and pyrite.Metallogenic can be divided into three stages:original sedimentary enrichment, tectonic hydrothermal transformation enrichment, and secondary weathering leaching. |
