Pyroxene辉石
Pyroxene is a silicate mineral with the general composition (Mg,Fe)SiO3. Though the basic formula is simple, it is said to be a complex class of minerals. The most common member of the group is augite, which forms dark crystals as a result of the iron and magnesium content. It is said to a ferromagnesian or "mafic" mineral which has a high crystallization temperature and is formed early in the Bowen reaction series. 辉石是一类含硅酸盐的矿物，其一般化学式为(Mg,Fe)SiO₃。尽管基本公式简单，但它被认为是一类复杂的矿物。该系列中最常见的成员是角闪石，由于铁和镁的含量，它形成暗色晶体。它被认为是一种铁镁质或'基性'矿物，具有较高的结晶温度，并在波文反应系列中较早形成。
The name pyroxene comes from the Greek words for fire and stranger. Pyroxenes were named this way because of their presence in volcanic lavas, where they are sometimes seen as crystals embedded in volcanic glass; it was assumed they were impurities in the glass, hence the name "fire strangers". However, they are simply early-forming minerals that crystallized before the lava erupted.(Wiki). Mindat: Pyroxene Mindat: 紫苏石
pyroxene 这个名称来源于希腊语中的‘火’和‘陌生人’。由于它们存在于火山熔岩中，有时可以看到它们作为晶体嵌在火山玻璃中；人们曾以为它们是玻璃中的杂质，因此称其为‘火的陌生人’。然而，它们只是在熔岩喷发前先结晶形成的矿物。 |
