| 摘 要： | 中国存在两种类型的VHMS型银矿床.其一为裂谷VHMS型银矿床，产于大陆裂谷构造环境中，受碱性橄榄玄武岩系列火山活动控制.银、铜为主要成矿元素；其二为岛弧VHMS型银矿床，产于岛弧带之上，其成矿作用与岛弧钙碱性系列火山活动关系密切.两种银矿床分别就位于粗安岩和流纹岩之中，它们的主成矿作用均发生于整个火山活动的晚期阶段.

| Abstract: | There are two kinds of VHMS silver deposits in China.The first is the rift VHMS silver deposit,which is tectonically located in continental rifts.This kind of silver mineralization is in control of volcanic activities of alkali dorgalite series.Ag and Cu are main mineralizing elements.The second is the island arc VHMS silver deposit located in island arcs.This kind of silver mineralization is closely related to volcanic activities of calcalkaline series.Ag,Pb and Zn are main mineralizing elements.The most important mineralization of the two kinds of silver deposits,which are hosted in trachyandesite and rhyolite,occured in the late stage of the whole volcanic activities. |
