| 摘 要： | 火山、次火山岩型银矿床储量约占全国银总储量的80％,是我国重要的银矿床类型。该类型矿床均分布于地洼区的不同构造单元的交接部位。结合地洼构造单元分区,将47个银矿床划分为东南、华中、五台—南兴安岭、吉辽、额尔古纳和滇西等6个银成矿区带。运用地洼成矿理论,初步总结了火山、次火山岩型银矿床产布,矿物组合,赋存形式和载体矿物以及成矿机构等方面的基本地质特征。

| Abstract: | The reserves of silver deposits in volcahic-subvolcanic rocks,an important type of silver ore deposit in china, account for 80% of the total reserves in our country. This type of ore deposits are distributed in the intersection portion between different tectonic units in diwa region. Combining with the diwa tectonic units in China ,47 silver deposits can be classified into 6 silver metallogenic belts:southeastern china,central of China,Wutai-southern Xi-nanlin Mts,Jilin-Liaoning Province, Eerguna and western Yunnan. By using the diwa metallogenic theory, the basic geological features, such as the ores occurence and distribution, mineral association, occuring form, loading minerals and metallogenic apparatus of the silver deposits in volcanic-subvolcanic rocks were primarily summarized. |
