5 Formation

5.1 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.

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

More about Eclogite and Rhyolite

Here you can know more about Eclogite and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Eclogite and Rhyolite 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 Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Eclogite vs Rhyolite, 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, Rhyolite is available in grey, white, light black colors. Appearance of Eclogite is Dull, Banded and Foilated and that of Rhyolite is Banded. Properties of rock is another aspect for Eclogite vs Rhyolite. The hardness of Eclogite is 3.5-4 and that of Rhyolite is 6-7. The types of Eclogite are Not Available whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Eclogite is white while that of Rhyolite is colorless.
