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.

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Latite and Granulite Properties

Know all about Latite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Latite belongs to Igneous Rocks while Granulite belongs to Metamorphic Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Granulite is Granoblastic. Latite appears Rough and Granulite appears Veined or Pebbled. The luster of Latite is subvitreous to dull while that of Granulite is vitreous. Latite and Granulite are available in black, brown, green, grey, pink, white 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 Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
