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.

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

All about Latite and Granodiorite Properties

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