| 摘 要： | 冀北银矿多属热液矿床。银矿的主要控制因素，除银本身的地球化学特性外，还包括以下４ 个方面：①具封闭条件或渗透率相对低的地层或岩层（ 岩石） ；②切割封闭体系或聚矿构造的新生性构造；③多期活动的火山－ 侵入杂岩体；④具深源特征的混合流体。成矿流体是最主要的控制因素，它是联系矿源、成矿地质背景和矿体的纽带。矿床形成的规模与产出状态与成矿流体的规模与产出状态密切相关

| Abstract: | In addition to its geochemical properties, the ore-controlling factors of silver deposits are summarised as: (1) enclosed environment or the strata with low permeability; (2) neo-structures cutting close system or ore-condensing structure; (3) multi-period magmatism; (4) existence of deeply-derived mixing fluid. The ore-forming fluid is the most important factor, which connects ore source, metallogenic setting and orebodies. The scale and occurrence of ore deposit is related to the ore-forming fluid. |
