摘　　要：蕉坑坞矿段位于浙江省八面山萤石矿田南东侧,为浙江省首次发现的新型萤石矿.17号矿体为该矿段的主矿体,赋存于花岗岩体接触面及其外接触带碳酸盐岩中.通过对该矿体的地质特征进行研究,并从岩浆岩、围岩和构造3方面讨论了矿床的控矿因素,认为矿床成因为岩浆期后热液充填矿床并伴随交代成矿作用,据此提出找矿标志.The Jiaokengwu fluorite ore block, located in the southeast of Bamianshan fluorite orefield in Zhejiang Province, is a new type of fluorite deposit discovered recently. The No.17 orebody is the main orebody, occurring in the contact with granite and the carbonate rock in the exocontact. Based on the study of geology and ore-controlling factors of the orebody, the characteristics of intrusion, wall rock and structures are discussed. It is concluded that the deposit was formed by the filling of post-magmatic hydrothermal fluid, accompanied by alteration. The prospecting indicators are put forward.
