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。
因此,铬尖晶石与辉石的共生连晶结构可以作为豆荚状铬铁矿的重要找矿标志。
超基性岩的SiO2含量小于45%,它的侵入岩叫做橄榄岩,主要由橄榄石、辉石等矿物组成。
主要的造岩矿物有橄榄石、辉石、斜长石、铬尖晶石、角闪石。
除了辉石质的主要矿物之外,翡翠的次要矿物主要是闪石和长石。
晶体中有时含方解石、石英、透辉石、绿帘石、方柱石、符山石和角闪石等矿物。
准噶尔盆地基底火山岩中的辉石及其对盆地基底性质的示踪
1·Despite this hint of water, however, these rocks still contained significant amounts of olivine and pyroxene.
不过,尽管有水的迹象,这里的岩石仍然含有大量的橄榄石与辉石。
2·The deformation of olivine and pyroxene in the rock is the recrystallized process from coarse to fine grain, the spinel has obvious dissolution, migration and reprecipitation.
岩石中橄榄石和辉石的变形都是由粗变细重结晶过程,尖晶石则有较明显的溶解、迁移和再沉淀作用。
3·A hard, dense, dark volcanic rock composed chiefly of plagioclase, pyroxene, and olivine, and often having a glassy appearance.
一种硬的、致密的、黑色的火山岩。它主要由斜长石、辉石和橄榄石组成,外表经常很光滑。
4·As magma cools, the first minerals to crystallize are olivine and pyroxene, which are rich in iron and magnesium.
随著岩浆冷却,首先结晶出的矿物是橄榄石和辉石,富含铁和镁。
5·According to the experimental result, we have analyzed the change of the crystal structure of pyroxene and olivine and the changing regula...
根据实验结果,定性分析了橄榄石、辉石晶体结构随温度变化及热力学参数的变化规律。
