crossite

Electron microprobe analysis shows that the glaucophanic amphiboles are represented by crossite formed at a pressure of 6.

经电子探针分析，蓝闪石类矿物为青铝闪石，形成时压力为６７×１０５ｋＰａ。

The first metamorphism ischaracterized by blueschist facies metamorphism in the early stage of Late palaeozoic,the second by glaucophane green schist facies metamorphism in the late stage of Late Palaeozoic,the third by the dynamic metamorphism controlled by fracturing,with veincrossite formed in the third.

对穆棱县的磨刀石、椅子圈地区的蓝片岩研究，确定其经受过三期叠加变质作用：第一期为蓝片岩相变质作用；第二期为蓝闪绿片岩相变质作用；第三期为受断裂构造控制的动力变质作用，形成脉状青铝闪石、钠长石等变质矿物。

Through detailed research on sample analysis result from energy spectrum,scanning electron microscope and ordinary optical microscope,an unusual amphibole mineral is discovered—magnesium rich arfvedsonite,sourcing from secondary alteration of titanite,which is a very unusual mineral metasomatic alteration phenomenon,that is,natrium and ma.

富镁亚铁钠闪石由榍石次生蚀变而来,是一种罕见的矿物交代蚀变现象,即榍石的钠铁闪石化,此现象对深层裂缝发育的砾岩带的储层演化研究有很大的意义。

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.

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。
