近年来，我国各地发现大量的砂岩型铜矿，一时间出现了寻找砂岩型铜矿的热潮。本文通过分析云南省宁蒗县砂岩铜矿的地层、构造、岩浆活动、沉积环境、化学组成，探求其矿床成因，认为区内三叠系砂岩和砂页岩在还原环境下有利于铜矿富集，喜马期的岩浆及热液活动是矿进一步富集的重要因素。

In recent years, plenty of sandstone type copper mines have been found in many regions in China, while the search for sandstone type copper deposits booms. Through the analysis of the strata, structure, magmatic activity, sedimentary environment and chemical composition of sandstone copper deposits in Ninglang county, Yunnan province, this article explores the genesis of deposits. The Triassic sandstone and sandy shale under the reduction environment are conducive to the enrichment of copper deposits and magma and hydrothermal activities of Himalayan period are important factors for further enrichment of ore.
