Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Carbonatite is intrusive or extrusive igneous rock which is defined by mineralogic composition, consisting of greater than 50 percent carbonate minerals

Etymology
From the Lherz Massif, an alpine peridotite complex, at Étang de Lers, near Massat in the French Pyrenees; Lherz is the archaic spelling of this location
From any intrusive igneous rock, having a majority of carbonate minerals

Formation
Lherzolite 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.
Carbonatites are intrusive or extrusive igneous rocks which are defined by mineralogic composition consisting of greater than 50 percent carbonate minerals and are formed due to low degrees of partial melting of rocks.

All about Lherzolite and Carbonatite Properties
Know all about Lherzolite and Carbonatite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite and Carbonatite belong to Igneous Rocks.Texture of Lherzolite is Grenue whereas that of Carbonatite is Granular, Poikiloblastic. Lherzolite appears Glassy, Vesicular and Foilated and Carbonatite appears Dull, Banded and Foilated. The luster of Lherzolite and Carbonatite is subvitreous to dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Carbonatite is available in black, brown, colourless, green, grey, pink, white colors. The commercial uses of Lherzolite are as armour rock for sea walls, source of magnesia (mgo), used in aquariums and that of Carbonatite are an oil and gas reservoir, as a feed additive for livestock, gemstone, metallurgical flux.
