Peridotite (US: / ˈ p ɛ r ɪ d oʊ ˌ t aɪ t, p ə ˈ r ɪ d ə-/ PERR-ih-doh-tyte, pə-RID-ə-) is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica.

Sep 4, 2023 · Peridotite is a type of ultramafic igneous rock that is primarily composed of the mineral olivine, along with smaller amounts of other minerals such as pyroxenes and amphiboles. It is one of the main rock types found in the Earth’s …

Peridotite is a generic name used for coarse-grained, dark-colored, ultramafic igneous rocks. Peridotites usually contain olivine as their primary mineral , frequently with other mafic minerals such as pyroxenes and amphiboles.

Jul 12, 2023 · Peridotite is a predominant rock in the Earth’s upper mantle at depths up to 400km, with only a minor yet important part of the Earth’s crust or surface. Depths beyond 400 km will convert olivine to wadsleyite.

A peridotite is an ultramafic rock containing more than 40% olivine (Mg 2 SiO 4). A general term for a coarse-grained plutonic rock composed chiefly of olivine with or without other mafic minerals such as pyroxenes, amphiboles, or micas, and containing little or no feldspar.

Peridotite is the ultimate source of all chromium ore and naturally occurring diamonds, and of nearly all chrysotile asbestos. It is one of the main host rocks of talc deposits and platinum metals and formerly was a major source of magnesite.

There are various physical properties of Peridotite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. The physical properties of Peridotite rock are vital in determining its Peridotite Texture and Peridotite Uses .

Peridotite is the dominant rock of the Earth's mantle above a depth of about 400 km. Below that depth, olivine is converted to a higher-pressure mineral. Oceanic plates consist of up to about 100 km of peridotite covered by a thin crust.

Peridotite (US: / ˈpɛrɪdoʊˌtaɪt, pəˈrɪdə -/ PERR-ih-doh-tyte, pə-RID-ə-) is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica.

May 8, 2018 · Peridotite is a dark-colored, coarse-grained igneous rock believed by many scientists to be the primary rock of the exterior of Earth's mantle. The rock typically forms in volcanic pipes and is forced to the surface from great depths during a volcanic eruption.
