Formation
Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
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.

All about Gabbro and Latite Properties
Know all about Gabbro and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Gabbro and Latite belong to Igneous Rocks.Texture of Gabbro is Phaneritic whereas that of Latite is Aphanitic to Porphyritic. Gabbro appears Veined and Shiny and Latite appears Rough. The luster of Gabbro is not available while that of Latite is subvitreous to dull. Gabbro is available in dark grey to black colors whereas Latite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
