Formation

Granite is an intrusive igneous rock which is very hard, crystalline and is visibly homogeneous in texture and forms by melting of continental rocks

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 Granite and Latite Properties

Know all about Granite and Latite properties here. All properties of rocks are important as they define the type of rock and its application. Granite and Latite belong to Igneous Rocks.Texture of Granite is Granular, Phaneritic whereas that of Latite is Aphanitic to Porphyritic. Granite appears Veined or Pebbled and Latite appears Rough. The luster of Granite is dull to grainy with sporadic parts pearly and vitreous while that of Latite is subvitreous to dull. Granite is available in black, grey, orange, pink, white colors whereas Latite is available in black, brown, green, grey, pink, white colors. The commercial uses of Granite are curling, gemstone, laboratory bench tops, tombstones, used in aquariums and that of Latite are an oil and gas reservoir, as a feed additive for livestock, metallurgical flux, soil conditioner, source of magnesia (mgo).
