摘　　要：通过对该区银矿床地质特征、成矿地质条件和成矿规律的研究，将区内银矿按成因、成矿作用、矿床地质特征等划分为三类六型。指出了火山－次火山热液型银矿是本区银矿的重要类型。总结了银矿的找矿标志，提出了本区银矿的主攻类型和主攻地区。even silver deposits and about 80 ore spots have been found in the volcanic terrain of Eastern Fujian, where is the major part of the Continental Volcanic Rock Belt in South China. This paper focuses on the ore-deposit characteristics, ore-forming conditions and metallogenic pattern of the silver ores found in the volcanic terrain of Eastern Fujian. According to the genesis, metallogenesis and ore-deposit characteristics, the silver ores in area can be divided into three kinds and six types, in which the volcanic-subvolcanic hydrothermal silver ores is an important type in the area. Finally, the authors put forward the major types and regions of prospecting silver ores in the volcanic terrain of Eastern Fujian.
