对浙江省青田县万山萤石矿床地质特征进行详细的野外调查和室内研究。矿床主要产于上侏罗统西山头组酸性火山碎屑岩的断裂构造中，空间分布上具有以燕山期侵入体为中心略呈环状分布的特点。结合前人研究成果，认为矿床属岩浆期后浅成低温热液充填型矿床。矿床的成因与燕山期火山、构造活动有关。

A detailed field exploration and lab research is carried out to study the geological characteristics of Wanshan fluorite deposits in Qingtian Country,Zhejiang Province. Ore deposits are mainly situated in the faults of Xishantou forma-tion,acidic pyroclastic rocks in Upper Jurassic. Spatial pattern shows circular distribution around Yanshanian intrusive bodies. Combining previous research results,the authors think the deposit belongs to a hypabyssal of low-temperature hy-drothermal filling type after magmatic activity deposit. The cause of deposit is related with Yanshanian volcanic and tec-tonic activities.
