This thesis studies the volcanic tectono-petrofacies, petrology, mineralogy, geochemistry, isotopic chronology, stratum and high-precision SHRIMP zircon U-Pb datings of the Mt.Yandangshan volcano-intrusive complex, and concludes that: Yandangshan volcanic rock units belong to high-K calc-alkaline acid rock associations, mainly ryholitic and trachytic dacitic in composition. They have A/CNK values of 0.9-1.2 (i.e., aluminium saturation and supersaturation), enriched LREE and LILEs and depleted HFSE. Their 8Eu values are 0.11-0.32, indicating a evident fractional evolution of plagioclase crystallization. Their ∑REE varied very limitedly,(87~Sr/(86)Sri ratios and eNd values are 0.7086～0.7095 and -10.20～-9.96 for volcanic rocks, and 0.7087~0.7095 and -7.6～6.92 for the central intrusive facies syenite, which means that all the igneous rocks from Mt. Yandangshan are evolutional products of magmas with the same source, and that they derived mainly from crust, but mixed with mantle components.

本文从火山构造岩相学、岩石学、矿物学、地球化学、同位素年代学、地层学等方面出发，同时结合高精度SHRIMP锆石U-Pb定年，对雁荡山火山岩进行了系统的研究，确定雁荡山火山岩为一套以流纹质和粗面英安质为主体的高钾钙碱性酸性岩石组合，A/CNK值集中在0.9～1.2之间，为铝饱和或铝过饱和类型；富轻稀土元素和大阳离子亲石元素、相对亏损高场强元素：负铕异常明显，δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用：岩石样品的∑REE变化有限，火山岩样品的~(87Sr/~(86)Sr_i为0.7086～0.7095，εNd为-10.20～-9.96，中央侵入体石英正长岩~(87Sr/~(86)Sr_i为0.7087～0.7095，εNd为-7.6～-6.92，表明它们是同源岩浆分异演化的产物，物质来源主要为陆壳，但有地幔物质参与。
