| 摘 要： | 金矿赋存于三叠系中统忙怀组上段第二层（T2m2-2）的蚀变安山岩的地层中,矿体受断层及火山岩双重控制,近矿围岩蚀变主要有硅化、黄（褐）铁矿化、毒砂化、方解石化等.认为该矿区金矿床成因类型为与火山作用、构造作用有关的蚀变岩型金矿床,并总结了矿区的找矿标志,对在该区域寻找该类型的金矿床具有一定的指导意义.

| Abstract: | The Au deposit is in the altered andesite of Middle Triassic Manghuai Formation Upper Member the second bed （T2m,2-2） . The orebody is controlled dually by fault and volcanic rock. The main alterations of wall rock near ore deposit are silicifieation, pyritization （limonitization）, arsenopyritization, calcitization, etc. We think it belongs to the altered rock type Au deposit related to volcanic and structure activities in genesis. We have summed up the prospecting criteria, which has a certain significance in prospecting of this type of Au deposit. |
