5 Formation
5.1 Formation
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Rhyolite vs Eclogite 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 Rhyolite and Eclogite Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature. 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 Rhyolite vs Eclogite information and Rhyolite vs Eclogite characteristics in the upcoming sections.

Rhyolite vs Eclogite 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. Rhyolite vs Eclogite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhyolite and Properties of Eclogite. Learn more about Rhyolite vs Eclogite in the next section. The interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Eclogite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Rhyolite and Eclogite, they have various applications in construction industry. The uses of Rhyolite in construction industry include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives and that of Eclogite include Not yet used.

More about Rhyolite and Eclogite

Here you can know more about Rhyolite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyolite and Eclogite consists of mineral content and compound content. The mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz and mineral content of Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all Igneous Rocks. When we have to compare Rhyolite vs Eclogite, the texture, color and appearance plays an important role in determining the type of rock. Rhyolite is available in grey, white, light black colors whereas, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Rhyolite is Banded and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Rhyolite vs Eclogite. The hardness of Rhyolite is 6-7 and that of Eclogite is 3.5-4. The types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. whereas types of Eclogite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhyolite is colorless while that of Eclogite is white. The specific heat capacity of Rhyolite is Not Available and that of Eclogite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Rhyolite is heat resistant, wear resistant whereas Eclogite is heat resistant.
