摘　　要：安徽省铁帽型金、银矿床在全国发现比较早,分布广,并且有一定规律,工业利用程度高,效益好。铁帽型金、银矿广泛产于各类型原生含Au、Ag硫化矿床的氧化带,以产于石炭系层状含(Cu)硫化矿床的上部氧化次生富集带规模较大,品位富。本次积累完整的矿床地质特征资料,探索矿床分类、氧化分带,研究金、银的赋矿规律和成矿条件,总结找矿标志和评价准则。The gossan-type gold and silver deposits in Anhui Province were found comparatively earlier in China, and are widely distributed in line with a certain law. They have been highly utilized industrially, therefore bringing good benefit. Gossan type gold and silver deposits widely occur in the oxidation belts of various Au and Ag-containing primary sulfide deposits, with those occurring in the upper oxidized secondary enrichment belt in Cu-containing layered sulfide deposit of carboniferous system being of large scale and high grade. In this paper a complete set of data on geological characteristics of the deposits are offered, and the ore deposit classification and oxidation zonation discussed, the gold and silver occurrence law, the mineralization conditions researched and the ore-prospecting signs and assessment criteria summarized.
