| 摘 要： | 浙东火山岩型银矿床属浅成中－低温火山热液成因。与成矿有关的火山岩、次火山岩具有富硅、贫铁、高钾、低钠特点。稀土元素表明，成矿火山岩与次火山岩是由地壳部分熔融形成的。同位素组成具岩浆成因特征。

| Abstract: | he volcanic type Ag mineral deposit belongs to hypabyssal medium-low temperature volcanic hydrothermal genesis. VoL-canic rocks and subvolcanic rocks related with metallogenesis are characteristic of rich Si,poor Fe,high K and low Na. It is indi-cated by studying REE that they are formed by partial melting of the crust,and that isotopic combination is characteristic of mag-matic genesis. |
