Pyroxenite is an ultramafic igneous rock consisting essentially of minerals of the pyroxene group, such as augite, diopside, hypersthene, bronzite or enstatite. Pyroxenites are classified into …

2023年4月23日 · Pyroxenite is an ultramafic igneous rock that contain pyroxene group minerals such as augite, diopside, hypersthene, bronzite or enstatite. This is a coarse-grained rock and …

pyroxenite, dark-coloured, intrusive igneous rock that consists chiefly of pyroxene. Pyroxenites are not abundant; they occur in discrete inclusions, in layered sills (tabular bodies inserted …

Pyroxenites are ultramafic intrusive igneous rocks composed almost entirely of dark Pyroxene group minerals rich in iron and magnesium, e.g., Augite, Diopside, Hypersthene, Diallage, …

辉石（pyroxene，augite）是一种常见的硅酸盐造岩矿物，广泛存在于 火成岩 和 变质岩 中，由硅氧分子链组成主要构架。 辉石主要分布在基性—超基性岩浆岩和变质岩中，晶型为短柱状， …

"Pyroxenites" is the name given to ultramafic rocks comprising >60% pyroxene. The term pyroxenite (s.s.) refers to a 'true' pyroxenite containing >90% pyroxene. A coarse-grained, …

2024年3月21日 · Pyroxenite is a dense, coarse-grained, dark-colored rock. Its color is primarily dark green or black, with mostly stubby prismatic pyroxene crystals. However, it may be …

A pyroxenite is an ultramafic plutonic rock consisting of ≫60% pyroxene (either clino- or orthopyroxene, or both). Other phases include olivine, hornblende, micas, garnet, feldspar, …

Pyroxenite is an ultramafic plutonic igneous rock. Ultramafic means that more than 90% of the rock is composed of magnesium- and iron-rich minerals like pyroxenes, amphiboles, and …

Pyroxenes are the most common single-chain silicate minerals. (The only other important group of single-chain silicates, the pyroxenoids, are much less common.) Their structure consists of …
