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

All about Latite and Gabbro Properties
Know all about Latite and Gabbro properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Gabbro belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Gabbro is Phaneritic. Latite appears Rough and Gabbro appears Veined and Shiny. The luster of Latite is subvitreous to dull while that of Gabbro is not available. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Gabbro is available in dark grey to black 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 Gabbro are cemetery markers, commemorative tablets, laboratory bench tops, jewelry, sea defence, tombstones.
