以会理红盆大铜厂矿区砂岩铜、银矿床为例 ,阐明该矿区液化沉积物构造的类型、特征、成因及其与成矿的关系和找矿上的应用 .矿区液化沉积物构造常见的有火焰构造、砂岩脉、砂球构造等 ,它们有较强的褪色化和矿化 ,可作为找矿标志 This paper takes the sandstone copper and silver deposits of Huaxian Dachang Copper Mine as an example to illustrate the types, characteristics, genesis and their relationship with the metallogenic relationship and the prospecting application of the liquefied sediments in this area. The flame structure, sandstone veins, sand ball structure, etc. They have a strong fade and mineralization, can be used as a sign of prospecting
