摘　　要：白银厂矿田黄铁矿型铜-多金属矿床是我国50年代初期勘查成功的大型矿床之一。在前人认识实践的基础上,概略叙述了本矿床的主要地质特征,重点论述了矿床形成的地质条件和物理-化学条件,以及成矿物质迁移富集的方式,指出矿床属火山-喷气成因的观点,为矿田深部找矿开拓了新思路。Pyritic-copper-polymetallic deposits in Baiyinchang ore—field are one of large scales oredeposit which were succesfully prospected at 1950s. On the basis of previous understanding, it is here briefly reported that the main geologic features, geologic and physical and chemical ore-forming conditions as well as ore-forming material migration-enrichment process of the deposits have been summarized. It is pointed out that the deposits are of volcanic exhalative origin and that this opened a new train of thoughts for ore prospection in the deep.
