摘要
运用傅立叶变换红外光谱技术 (FTIR,红外区和近红外区 )和质子魔角旋转核磁共振技术 (1 H MAS NMR)对来自安徽女山、江苏盘石山和河北汉诺坝新生代碱性玄武岩中的 4个歪长石巨晶进行了观察 ,结果显示 ,这些巨晶含有结构水 ,主要以 H2 O的形式存在 ,其中 3个样品的结构水含量 (H2 O)分别为 40 5μg/ g,915μg/ g和 36 5μg/ g。这些数据和文献中已有的资料表明 。
Four anorthoclase megacrysts from Cenozoic alkalic basalts from Nushan, Anhui province, Panshishan, Jiangsu province and Hannuoba, Hebei province have been investigated by FTIR and 1H MAS NMR. The spectra show that these samples contain structural hydrogen which occur as H 2O. The water contents of three megacrysts are 405μg/g, 915μg/g和365μg/g respectively?Combining these values with previously reported data, it seems that nominally anhydrous feldspards could be a part of water reservoir of the earth.
