钠闪石

钠闪石花岗岩的Rb－Sr等时线年龄为125Ma。

Riebeckite granites emplaced in Jurassic volcanic basin of Da Hinggan Ling and its Rb Sr isochron age is 125 Ma .

沉积岩中镁钠闪石石棉矿物的初步研究

Magnesian riebeckite asbestus from sedimentary rocks & a preliminary study

因52个样品中，也包含钠钙闪石亚族，故对整个闪石族用X射线衍射估算阳离子占位的问题已基本解决。

As Na-Ca sub-amphiboles appeared among the52 samples , the method of estimating canon occupancied by X-ray diffraction is suitable to all amphiboles .

利用岩石薄片X衍射技术，在松辽盆地深层富碱酸性火山岩中识别出特征的碱性暗色矿物&钠铁闪石，从而确定其为碱流岩。

Using thin section X-ray diffraction techniques , his paper identified arfvedsonite in volcanic rocks from Songliao Basin , and thus confirmed that the volcanic rocks are composed of pantellerite .

本文还从霓石、钠铁闪石的结构、生长条件方面的差异对其形貌差异进行了对比分析。

Through the analysis of the difference in structure and growth condition between aegirine and arfvedsonite , the differ-ence in morphology and surface microtopography between these two minerals has also been ana-lysed .

具交代结构的翡翠中常因含有钠质闪石、钠长石或绿泥石，且使翡翠的粒度不均匀而使其质量变差；

The jadeite 's quality with the micro-crystalloblastic fiber texture is high , whereas that with the metasomatic texture is poor because there are sodium amphibole , albite or chlorite in it .

Origin and evolution of sodium amphibolite in metamorphic basic volcanic rocks from Yongquan area of Heilongjiang

这些基性火山岩至少发生了两期高压变质，两期高压变质形成的钠质角闪石具有不同成因。

These basic volcanic rocks underwent high pressure metamorphism for two times , at least , in which sodium amphibolites are formed by high pressure metamorphism with different genesis .
