| 摘 要： | 在运用常规方法和激光烧蚀同位素分析方法分别对云霄晶洞花岗岩和伟晶岩(长石、石英和石榴子石)的硅、氧同位素组成进行研究的基础上,探讨了晶涧花岗岩及其含石榴子石伟晶岩的物质来源及形成条件.伟晶岩中的石英和长石的氧、硅同位素组成分别较之花岗岩中的石英和长石的氧、硅同位素组成,均未发生明显变化,表明二者岩浆来源一致.云霄县的乌...

| Abstract: | The oxygen and silicon isotopic compositions of minerals(quartz,feldspar and garnet) from the miarolitic cavity granites and pegmatites in Yunxiao county,Fujian province,are measured by using conventional method and laser probe analytic method for determining their material sources and forming conditions.The oxygen and silicon isotopic compositions of quartz and feldspar from the pegmatites are very similar to those of the granites,indicating that they have the same magma source.The Wushan granite in Yunxia... |
