摘要: 对我国单一银(-金)矿床地质特征、成因类型和空间分布特点进行了总结.以成矿作用和成矿地质条件为基础,矿床成因为依据,我国单一银(-金)矿床可分为:(1)变质(混合岩化)热液型矿床;(2)火山(含次火山)热液型银(-金)矿床;(3)岩浆-热液型银(-金)矿床;(4)地热水溶滤型银(-金)矿床.Abstract: Based on the metallogenesis and ore-forming conditions, the geological characteristics, genesis types and spatial distribution of the single silver (-gold) deposits in China are summarized. The single silver (-gold) deposits in China can be genetically classified into four types, which are (1) metamorphic (migmatized) hydrothermal deposits; (2) volcanic (subvolcanic) hydrothermal deposits; (3) magmatic hydrothermal deposits; and (4) geothermal water leaching deposits.
