摘要
南澜沧江火山岩成矿带位于特提斯亚构造域(东段)之澜沧江晚古生代-三叠纪火山岩浆弧带。成矿带构造复杂,岩浆活动频繁,矿产资源丰富,矿种和类型多,具有良好的成矿地质条件。成矿带内铜矿类型有火山岩及火山沉积型铜矿床;与酸性侵入岩有关的热液脉状型、矽卡岩型和斑岩型铜矿床,以及复合成因的脉状铜矿床。介绍了区带内相继发现的一批以海相火山岩型(大平掌、三达山等)、热(卤)水沉积-改造型和斑岩-火山岩型(民乐铜矿)为主的大、中型铜矿床;展望了澜沧江火山岩成矿带具有寻找火山岩型铜矿的良好前景。
The volcanic rock metalloganic belt in the south Lancang River region is characterized by the complex geological structure, frequent magmatism, abundant mineral resources and various sorts and types of minerals. In the metallogenic belt there exist copper deposit in volcanic rock and in volcanic deposit, acidic intrusive?-related hydrothermal vein copper deposit, skarn and porphyry copper deposite as well as the vein copper deposit with complex origin. The paper introduces some large and medium sized copper deposits and shows the perspective of prospecting of volcanic rock type copper deposit in that metallogenic belt.
