~ ( 40 ) ar / ~ ( 39 ) ar plateau age spectra of feldspars and Their Geological Implications

裂隙水中常量元素和微量元素主要来源于长石类矿物的水解，特别是钙长石的水解，其中SiO2和Sr在裂隙水中含量较高，已达到饮用矿泉水标准。

The common elements and trace elements in crevice water are mainly derived from hydrolysis of feldspars , especially anorthite . The contents of SiO2 and Sr in crevice water are relatively high and have met the standards of drinking mineral water .

长石类矿物析碱对碱-硅酸反应的影响

Alkali Release from Feldspathic Mineral and the Effect in Alkali-silica Reaction

研究结果表明，细砂粒和粉粒中的矿物以石英为主，含少量长石和云母类矿物。

It showed that sand and silt contained a large amount of quartz , and a small amount of feldspar and mica minerals .

应用热力学方法探讨了混凝土集料中钾长石、钠长石、霞石等长石类含碱矿物的热力学稳定条件，并对这些含碱矿物分解析出的碱对AAR（碱集料反应）的影响进行了讨论。

The resolution reaction in alkali solution of feldspathic mineral , such as potash feldspar , albite and nepheline , is studied by thermodynamics , and the possibility of alkali released from feldspathic mineral and the effect to AAR are analyzed also .
