摘    要：华南广泛发育有晚古生代断拉谷。许多重要的铜多金属矿床分布其中。这些矿床尽管地理分布位置相差较大,但都具有明显的多因复成特征,属地台阶段沉积(或火山沉积)成矿作用+地洼阶段岩浆热液(或混合热液)迭加、改造富集型。断拉谷对其中铜多金属矿床的形成起了“奠基”和“铺路”的重要作用。

Abstract: South China has experienced at least three stages: geosynclinal, platform anddiwa. At the platform stage late Paleozoic aulacogens were extensively developed. Many important copper-polymetal deposits occur in these aulacogens. Although these ore deposits occur geographically far from each other, they are similardistinctly in polygenetic compound mineralization features, which are sedimentary or volcanic-sedimentary mineralization in platform stage plus magmatic hydro-thermal richening mineralization in diwa stage. The paleo-aulacogens of South China played an important role in "laying a foundation" and "paving a road"to form these deposits.
