Definition
Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

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 French, Greek eklogē selection with reference to the selective content of the rock + -ite1

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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

All about Lherzolite and Eclogite Properties
Know all about Lherzolite and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Lherzolite belongs to Igneous Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Lherzolite is Grenue whereas that of Eclogite is Earthy. Lherzolite appears Glassy, Vesicular and Foilated and Eclogite appears Dull, Banded and Foilated. The luster of Lherzolite and Eclogite is subvitreous to dull. Lherzolite is available in black, dark greenish - grey, green, pink, purple colors whereas Eclogite 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 Eclogite are creating artwork, gemstone.
