摘　　要：赞比亚是世界著名的铜产地之一,其铜矿类型可分为层控型、沉积型、变质改造型及热液型,以沉积型为主。据现有大中型矿床铜资源量统计,沉积型矿产铜资源量占赞比亚铜总资源量的79%。各类型铜矿床总体受卢弗里安(Luflian)弧控制,层控型铜矿主要分布在穹窿核部边缘,含矿岩系为莫瓦(Muva)超群的黑云母片岩、二云石英片岩;沉积型铜矿主要分布在背斜或穹窿外缘周围,含矿岩系主要是加丹加(Katanga)超群下部的砂页岩层。Zambia is one of the most famous copper production places in the world. The copper ore deposits in Zambia include stratabound, sedimen-tary, metamorphosed-deformation and hydrothermal types, and are dominated by the sedimentary type. Statistics indicate that the sedimentary copper ore resources account for 79% of the whole resources in Zambia. All kinds of the copper ore deposits are controlled by the Luflian arc. The stratabound copper deposits are mainly discovered in the perifornieal region, and the ore-bearing rock serious are the Muva megagroup biotite schist and around the anticlines and two-mica quartz schist. The sedimentary copper deposits are mainly distributed around anticlines and the peripheral dome, and the ore-bearing rock series are the lower Katanga megagroup sandstone-shale beds.
