WebNoun. (geology, mineralogy) A rock consisting of small crystals of olivine, pyroxene and hornblende; the major constituent of the Earth's mantle. *:Varieties of peridotite' are distinguished by their mineral composition; for example, dunite is a ' peridotite which is virtually all olivine, and a dense, dark green in colour. http://www.alexstrekeisen.it/english/pluto/peridotites.php

WebFirst, chromite is one of the more weathering-resistant minerals of peridotite. That causes it to be concentrated in residual soils that form in the weathering zone above chromite-rich rocks. Second, chromite has a higher specific gravity than other minerals in peridotite. WebPeridotite is a dense, coarse-grained igneous rock, consisting mostly of the minerals olivine and pyroxene. This rock is derived from the Earth's mantle. Its composition varies, depending on the mineral content of the rock. Generally, it is rich in magnesium, with appreciable amounts of iron, and less than 45 percent silica.
WebBegonia peridoticola fait partie de la section Baryandra du genre Begonia, famille des Begoniaceae 2 . L'espèce a été décrite en 2015 par les botanistes Ching I Peng, Repin Rimi et Che Wei Lin. L' épithète spécifique peridoticola est une référence à la péridotite présente dans les falaises de Bat Cave où elle a été collectée. WebMetasomatism (from the Greek μετά metá "change" and σῶμα sôma "body") is the chemical alteration of a rock by hydrothermal and other fluids. [1] It is the replacement of one rock by another of different mineralogical and chemical composition. The minerals which compose the rocks are dissolved and new mineral formations are deposited ...

Peridotite 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. It is high in magnesium (Mg ), reflecting the high proportions of magnesium-rich olivine, with appreciable iron. Peridotite is … See more Coarse-grained igneous rocks in which mafic minerals (minerals rich in magnesium and iron) make up over 90% of the volume of the rock are classified as ultramafic rocks.

These magmas are … See more Peridotite may potentially be used in a low-cost, safe and permanent method of capturing and storing atmospheric CO2 as part of See more Mantle peridotite is highly enriched in magnesium, with a typical magnesium number of 89. In other words, of the total content of iron plus magnesium, 89 mol% is magnesium. This is reflected in the composition of the mafic minerals making up the peridotite. See more Most peridotite is green in color due to its high olivine content. However, peridotites can range in color from greenish-gray to nearly black to pale yellowish-green. Peridotite weathers … See more Komatiites are high temperature partial melts of peridotite characterized by a high degree of partial melting deep below the surface. Eclogite, … See more
