火山热液型矿床具有重要的工业价值,在我国东南部分布广泛且经常成群出现。上下湖锡铜多金属矿点位于闽西南晚古生代拗陷之胡坊—永定隆起南端与上杭—云霄北西向深大断裂交汇部位。区内岩浆活动强烈,火山断裂、次火山岩发育,是锡铜多金属成矿有利区域。本文通过对该矿点控矿因素及矿床成因类型综合分析,认为该矿点为火山热液型矿床,对在该地区寻找火山热液型锡铜矿具有积极的找矿意义。
Volcanic hydrothermal deposits have important industrial value, widespread in the southeast of China and often appear in groups. The upper and lower lake tin-copper polymetallic ore deposits are located in the junction of Hufang-Yongding Uplift and the intersection of Shanghang-Yunxiao Northwest-West Deep Fault in the Late Paleozoic depression of southwest Fujian. Magmatic activity in the area is strong, volcanic rupture, secondary volcanic rock development, tin-copper polymetallic mineralization is a favorable area. Based on the comprehensive analysis of the ore-controlling factors and genetic types of the deposit, the paper considers the deposit as a volcanic hydrothermal deposit and has a positive prospecting significance for finding volcanic hydrothermal tin-copper deposits in this area.
