Formation

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

All about Latite and Pyroxenite Properties

Know all about Latite and Pyroxenite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Pyroxenite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Pyroxenite is Clastic, Granular, Phaneritic, Porphyritic. Latite appears Rough and Pyroxenite appears Layered, Banded, Veined and Shiny. The luster of Latite is subvitreous to dull while that of Pyroxenite is dull to vitreous to submetallic. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Pyroxenite is available in black to grey, bluish - grey, dark greenish - grey, green, light greenish grey colors. The commercial uses of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo) and that of Pyroxenite are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
