The first type, kamafugite, is plagioclasefree, consisted of Tirich phlogopite, melilite, leucite and nephelite. They have lower contents of SiO2 and Al2O3, but have high TiO2, CaO, MgO contents and K/Na and Mg# ratio whereas the second type, potassic trachybasalt, is abundant in plagioclase and contains no phlogopite, melilite, leucite and nephelite. They have higher SiO2, Al2O3,(Na2O+K2O), and lower TiO2, CaO, MgO, and K/Na and Mg#, in comparision to the first type of rocks.

钾霞橄黄长岩是一种不含斜长石，但普遍含有高钛金云母、黄长石、白榴石、霞石的岩石，全岩化学成分具低SiO2和Al2O3，富TiO2、CaO、MgO和高K/Na、高Mg#值的特征；钾质粗面玄武岩含有大量斜长石但是缺乏高钛金云母、黄长石、白榴石和霞石，全岩化学中SiO2、Al2O3明显高于前者，而TiO2、CaO、MgO、K/Na和Mg#值要比钾霞橄黄长岩低。

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。

The wolframite, scheelite, tantalum niobite and fine spar have uneven distribution in the raw ores. Relatively, the wolframite and scheelite have coarse embedded granularity, generally 0.8 ~ 0.04 mm. The tantalum niobite and fine spar have fine embedded granularity, generally 0.2 to 0.04 mm.

原矿中黑钨矿、白钨矿、钽铌铁矿、细晶石的嵌布粒度皆为不均匀嵌布，黑钨矿与白钨矿的嵌布粒度相对较粗，一般为0.8~0.04毫米，而钽铌铁矿及细晶石的嵌布粒度则很细，一般为0.2~0.04毫米。

It works by choosing appropriate gravel, scree, talus decries, coarse sand, medium sand, then ram them to be closely knitted. The sand gravel cushion can increase the bearing capacity of weak groundwork.

这种垫层法是用碎石、卵石、角砾、圆砾、砾砂、粗砂、中砂或石屑等坚硬、较粗粒径的回填材料，经合理级配并夯压密实后形成持力垫层，其主要目的是为了提高浅层软弱地基或不均匀地基的承载力。
