1.1 Definition

Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine

Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

5 Formation

5.1 Formation

Pyroxenites are ultramafic igneous rocks which are made up of minerals of the pyroxene group, such as augite and diopside, hypersthene, bronzite or enstatite.

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

All about Pyroxenite and Metapelite Properties

Know all about Pyroxenite and Metapelite properties here. All properties of rocks are important as they define the type of rock and its application. Pyroxenite belongs to Igneous Rocks while Metapelite belongs to Metamorphic Rocks.Texture of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic whereas that of Metapelite is Foliated. Pyroxenite appears Layered, Banded, Veined and Shiny and Metapelite appears Banded. The luster of Pyroxenite is dull to vitreous to submetallic while that of Metapelite is earthy. Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors whereas Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. The commercial uses of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Metapelite are commemorative tablets, creating artwork.
