Lherzolite vs Eclogite


Definition

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

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

Formation

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

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Eclogite and Lherzolite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Lherzolite is a type of ultramafic igneous rock which contains essential olivine and clinopyroxene and orthopyroxene in equal proportions. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Eclogite vs Lherzolite information and Eclogite vs Lherzolite characteristics in the upcoming sections.

More about Eclogite and Lherzolite

Here you can know more about Eclogite and Lherzolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Lherzolite consists of mineral content and compound content. The mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite and mineral content of Lherzolite includes Harzburgite, Olivine, Pyroxene, Pyrrhotite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Lherzolite, the texture, color and appearance plays an important role in determining the type of rock. Eclogite is available in black, brown, colourless, green, grey, pink, white colors whereas, Lherzolite is available in black, dark greenish - grey, green, pink, purple colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Lherzolite is Glassy, Vesicular and Foilated. Properties of rock is another aspect for Eclogite vs Lherzolite. The hardness of Eclogite is 3.5-4 and that of Lherzolite is 6.5. The types of Eclogite are Not Available whereas types of Lherzolite are Garnet Lherzolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Lherzolite is white.
