摘　　要：在分析总结浙江青田县山口矿区叶蜡石矿床特征和蚀变分带特征的基础上,对矿床成因进行研究,结果表明,山口矿区自上而下分为4个相带,即石英相带、叶蜡石石英相带、绢云母石英相带、黄铁矿石英相带,叶蜡石矿主要分布在叶蜡石石英相带,呈似层状,控矿因素为火山构造洼地、火山碎屑岩、潜火山岩等,矿床类型为火山气成-热液交代蚀变型矿床。Based on the analysis and summary of the alteration zoning characteristics of pyrophyllite deposit in Shankou mining area of Qingtian County,Zhejiang Province,the deposit genesis is studied.The result shows that Shankou mining area can be divided into four face zones from top to bottom,namely quartz face zone,pyrophyllite quartz face zone,sericite quartz face zone and pyrite quartz face zone.The pyrophyllite deposit is mainly distributed in the pyrophyllite quartz face zone,which is in layered shape.The ore-controlling factors are volcanic structural depression,volcanic clastic rock and subvolcanic rock.The deposit type is a volcanic gas hydrothermal metasomatic alteration type deposit.
