滇东南海相火山岩型铜矿系统研究程度较低，找矿潜力较大。区内3个典型铜矿床地质特征及地球化学研究表明，它们均为与海相火山岩有关的火山沉积改造型铜矿床。矿体受地层层位控制，与中三叠世含矿变基性火山岩系关系密切。同时，矿体受后期构造和热液改造，经历了强烈的变质作用，矿区侵入岩可能为矿体的二次富集提供了热液和物质来源。3个矿区的火山岩具有共性，都具备成为矿源层的条件，但成岩微构造环境有一定差异。区内找矿潜力较大，在加强深部找矿的同时，应重视火山岩的系统综合研究，以选定新靶区。

The systematic study of the marine volcanic type copper deposits in southeast Yunnan Province is relatively insufficient, and the prospecting potential for this type of ore deposit is very promising in this area. Researches on three typical copper deposits show that they all belong to volcanic-sedimentary reformation type copper deposits related to marine volcanic rocks, and that ore bodies were controlled by stratigraphic horizons and gradually reformed into economic ore bodies by tectonic and hydrothermal activities. Volcanic rocks in the three studied ore deposits show some generality and all possess the conditions to serve as the ore resource beds;nevertheless, their rock-forming microstructural environments are somewhat different from each other. The ore-prospecting potential is fairly great in this area and, while strengthening the work of deep prospecting, we should also pay attention to the systematic and integrated study of the volcanic rocks so as to delineate new target areas.
