摘　　要：安徽庐枞盆地是长江中下游成矿带重要的铁铜多金属矿集区,是研究与火山-次火山岩有关的多金属矿床的优良地区。脉状铜矿床作为盆地中矿床的主要类型,研究较为薄弱,制约了对该类型矿床成矿机理的深入认识。本文选择杀虎台脉状铜矿床,开展了矿床地质特征及流体包裹体的研究工作,明确其为与火山-次火山活动有关的中低温(170~260℃)中等盐度(11.0%~19.0%)热液充填型矿床,并对成矿作用过程进行了初步探讨。As an important iron, copper polymetallic ore deposit cluster area in the mid-lower Yangtze reaches metallogenic belt, the Lu-Zong basin, Anhui is a superior area for study of polymetallic ore deposits related to volcanic-subvolcanic rocks. Vein-like copper ore deposits are major types of ore in the basin, study of which is insufficient, thus restricting further understanding of their formation mechanism. This paper chose the Shahutai vein-like copper ore deposit as a subject for study of ore deposit geological features and fluid inclusions. It was defined as a mid-low temperature（ 170-260℃）and medium salinity （ 11.0%-19.0% ）hydrothermal filling deposit related to volcanic-subvolcanic activities, with its ore-forming process being discussed initially.
