含钠长石硅质岩、千枚岩、灰岩组合是找矿评价的重要标志。
长石矿物特别是钠长石作为翡翠的常见次要矿物,与硬玉矿物之间存在着密切的关系。
钠质交代岩的蚀变强度可分为两级:钠化闪长岩类和钠长石岩。
在这些条件下出现的典型矿物有沸石、钠长石、石英和葡萄石。
1·There are quartz, sericite, muscovite, albite and carbonate in near-ore altered rocks.
近矿蚀变岩石中存在石英、绢云母、白云母、钠长石和碳酸盐。
2·Mineral constituents consist mainly of jadeite, aegirine - augite, magnesio - riebeckite, winchite, magnesio - hornblende, actinolite, quartz, albite, rutile and sphene.
主要组成矿物为硬玉、霓辉石、镁纳闪石、蓝透闪石、镁角闪石、阳起石、 石英、 钠长石、金红石和榍石。
3·Mineral constituents consist mainly of jadeite, aegirine - augite, magnesio - riebeckite, winchite , magnesio - hornblende , actinolite , quartz, albite, rutile and sphene.
主要组成矿物为硬玉、 霓辉石、 镁纳闪石、蓝透闪石、镁角闪石、阳起石、 石英、 钠长石、 金红石和榍石。
4·The associated quartz and albite are also commonly identified as thermal-water minerals.
伴生的石英和钠长石亦为常见的热水矿物。
5·Under scanning electron microscope, barite in these samples occurs as euhedral crystal, co-existing with authigenic quartz and albite with the same idiomorph.
扫描电镜观察发现,重晶石均为完整自形晶,并与同为自形的石英及钠长石共生。
