Research about ore-forming fluids on it is still lacking. This study made a systematic investigation of fluid inclusions in the Jiande copper deposit. Based on petrographic observations of ore-bearing quartz collected from the massive ores, there are three types of primary inclusions of Jiande deposit: two-phase liquid-rich (type I), two-phase vapor-rich (type II), and halite-bearing (type III) fluid inclusions. Type I inclusions occur widely in the Jiande %K 流体包裹体< %K /br> %K 显微测温 %U http://geology.nju.edu.cn/CN/abstract/abstract9745.shtml
