All about Latite and Lherzolite Properties
Know all about Latite and Lherzolite properties here. All properties of rocks are important as they define the type of rock and its application. Latite and Lherzolite belong to Igneous Rocks.Texture of Latite is Aphanitic to Porphyritic whereas that of Lherzolite is Grenue. Latite appears Rough and Lherzolite appears Glassy, Vesicular and Foilated. The luster of Latite and Lherzolite is subvitreous to dull. Latite is available in black, brown, colourless, green, grey, pink, white colors whereas Lherzolite is available in black, dark greenish - grey, green, pink, purple 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 Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums.
