Phonolite vs Eclogite


Definition

Definition
Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature   
Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic   

History
  
  

Discoverer
René Just Haüy   
Unknown   

Etymology
From French, Greek eklogē selection with reference to the selective content of the rock + -ite1   
From the Greek meaning sounding stone because of the metallic sound it produces if an unfractured plate is hit

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.   
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Eclogite vs Phonolite 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 Phonolite Reserves. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. 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 Phonolite information and Eclogite vs Phonolite characteristics in the upcoming sections.

Eclogite vs Phonolite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Eclogite vs Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Eclogite and Properties of Phonolite. Learn more about Eclogite vs Phonolite in the next section. The interior uses of Eclogite include Decorative aggregates and Interior decoration whereas the interior uses of Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Eclogite and Phonolite, they have various applications in construction industry. The uses of Eclogite in construction industry include Not yet used and that of Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.

More about Eclogite and Phonolite

Here you can know more about Eclogite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Phonolite 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 Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Eclogite vs Phonolite. The hardness of Eclogite is 3.5-4 and that of Phonolite is 5.5-6. The types of Eclogite are Not Available whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite and Phonolite is white. The specific heat capacity of Eclogite is Not Available and that of Phonolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Eclogite is heat resistant whereas Phonolite is heat resistant, impact resistant, wear resistant.
