摘　　要：广东丰顺上礤叶蜡石矿床成因类型属火山气液型(次生石英岩型),受层位和区域性断裂控制,与围岩呈渐变过渡关系,属流纹质凝灰岩等在构造和热液作用下蚀变而成。叶蜡石矿(化)体赋存于晚侏罗系热水洞组第四段英安质角砾凝灰岩夹流纹质凝灰岩透镜体内,呈透镜状北东-南西向展布,倾向北西。侏罗系凝灰岩中构造透镜体化和硅化(次生石英岩化)可作为间接找矿标志。The Shangcapyrophyllite deposit in Fengshun,Guangdong is of volcanic hydrothermal type.It is controlled by stratigraphic layers and regional faults,and is formed by hydrothermal alteration and tectonic deformation of rhyolitic tuff.The orebodyis lenticularandhosted within the Fourth Member of the Late Jurassic Redishuidong Formation,specifically in dacitic breccia tuff intercalated with rhyolitic tuff lenticular body,striking NE-SW and dipping to NW.Tectonic lentoid bodies and silicification in Jurassic tuff can serve as indirect oreprospecting indicators.
