所有辉石是透辉石质普通辉石,其成分相对近于透辉石--镁铁辉石。
矿渣微晶玻璃的主析晶相为钙铁辉石,次晶相为普通辉石和紫苏辉石;
此岩系由黑色或暗灰色橄榄石、普通辉石玄武岩、角闪石安山岩等大小石块构成。
1·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。
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·The groundmass has the same mineral components as phenocryst, and is composed of plagioclase, augite and olivine.
电子探针成分分析显示,基质矿物组成与斑晶矿物组成相同,均是由斜长石、辉石和橄榄石组成;
4·Augite monzonite crystallized at high-temperature and over-hypabyssal conditions. The water-deficient, highly viscous magma was favourable to the formation of the volcanic dome.
辉石二长岩形成于高温、超浅成的环境下,贫水、粘度较高的岩浆有利于火山穹窿的形成。
