紫苏辉石
Sign in to saveHypersthene is a common rock-forming inosilicate mineral belonging to the group of orthorhombic pyroxenes. Its chemical formula is . It is found in igneous and some metamorphic rocks as well as in stony and iron meteorites. Many references have formally abandoned this term, preferring to categorise this mineral as enstatite or ferrosilite. It forms a solid solution series with the minerals enstatite and ferrosilite, being a mid-way member between the two. Pure enstatite contains no iron, while pure ferrosilite contains no magnesium; hypersthene is the name given to the mineral when a significa

紫苏辉石（Hypersthene）是一种常见的成岩链硅酸盐矿物，隶属于正交辉石族，其化学式为(Mg,Fe)SiO3。它存在于火成岩和一些变质岩以及石质和铁质陨石中。许多参考文献已正式放弃了这一术语，而更倾向于将该矿物归类为顽火辉石或铁辉石。它与顽火辉石和铁辉石矿物了构成了固溶体系列，是两者间的中间成员。纯顽火辉石不含铁，而纯铁辉石不含镁，紫苏辉石则是两种元素都存在时的矿物名称。 明显发育的晶体非常罕见，这种矿物通常以叶状块嵌入在苏长岩火成岩和紫苏辉石-安山岩中，是其中的基本成分。拉布拉多海岸附近保罗岛的粗粒富拉玄武岩-紫苏辉石-苏长岩提供了最典型的材料，由于这一原因，这种矿物被称为拉布拉多角闪石或保罗石。 紫苏辉石颜色通常为灰、棕或绿色，带有玻璃至珍珠般光泽，多色性强烈，硬度5-6，比重为3.4-3.9。在部分表面显示出明亮的铜红色金属光泽或席勒光泽，与的青铜光泽来源相同，但更为明显。像古铜辉石一样，它有时被切割和抛光成宝石。 “紫苏辉石”这个名称来源于希腊语，意思是“超强度”，暗指它比闪石矿物角闪石（一种经常被混淆的矿物）更硬。 紫苏辉石一词现已被国际矿物学协会弃用。
