摘要
我国东部地区银矿床赋矿层位以古生界和中生界为主。具有“矿源层”特征；与成矿关系密切的岩体是燕山期中酸性－酸性小岩体；不同类型银矿床中的元素组合以Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ和Ａｓ为主，并各有特征元素；成矿温度属于中低温型；成矿物质具多源性。
The host beds of silver deposits in the eastern China are mainly Palaeozoic and Mesozoic Erathem which are charactered as “mineral resources bed”.Magmatic intrusions closely related to the mineralization are some small intermediate acid and acidic intrusive rocks in Yenshan epoch.The paragenetic association of elements in different type silver deposits are mainly Ag,Cu,Zn,Pb and As.The deposits belong to epithermal-mesothermal type in their minerogenic temperature.Their mineralization elements are charactered by multiple sources.
