Hornblendite is a plutonic rock consisting mainly of the amphibole hornblende. Hornblende -rich ultramafic rocks are rare and when hornblende is the dominant mineral phase they are classified as hornblendites with qualifiers such as garnet hornblendite identifying a second abundant contained mineral.

A hornblendite is an ultramafic igneous rock dominated by hornblende. It is different from an amphibolite which is a amphibole and plagioclase dominated metamorphic rock. Horblendite is a rare rock most commonly associated with diorite, granite, gabbro and peridotite.

Hornblendite: Mineral information, data and localities. This page is currently not sponsored. Click here to sponsor this page. An ultramafic plutonic rock composed almost entirely of hornblende. …

Oct 1, 2020 · Rare Bolivian hornblendites record ‘cryptic’ fractionation of amphibole at arcs. Mesocumulate textures confirm their formation as a cumulate pile in the arc crust. Geochemical evidence is consistent with hornblendites' origin from mid-lower crust. Oxy-exsolution ilmenite lamellae records late-stage cooling of hornblendites.

Apr 5, 2024 · Hornblendites from the Gangdese arc magmas provide useful information on deep-seated magma differentiation (Xu et al., 2019) and metasomatism associated with upper crustal copper deposits (Zhu et al., 2022).

角闪石岩 （英語： Hornblendite）是一种超 镁 铁 岩石，主要是由 角闪石 组成，含量超过90%，成分包含 钠 、 钙 、镁、铁、 铝 、 硅 等 氧化 物和 氢 氧化物。 也有时含有少量的 辉石 和 橄榄石，伴生的 矿物 主要有含 钒 的钛 磁铁矿。

Hornblendite is an ultramafic rock (dominantly dark minerals). True hornblendites contain little other than amphibole and are probably derived from the alteration of pyroxene and olivine.

Apr 1, 2021 · The hornblendite and pyroxenite cumulates constitute high P-wave velocity body (27–15 km depth) in the middle crust of northern East Junggar. The Early-Permian formation of the main pluton is a complex process.

Hornblendite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Hornblendite is a rare igneous rock containing large amounts of hornblende, which is a combined group of dark-colored amphibole minerals. Hornblendite is often found alongside diorite, granite, gabbro, and peridotite. While uncommon, this rock is used for kitchen countertops, garden walkways and decoration, as well as entryway and flooring ...
