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.

Kimberlite is an igneous rock and is the main source of diamonds. Its formation takes place deep beneath the Earth’s surface between 150 to 450 kilometres, and are erupted rapidly and violently.

More about Rhyolite and Kimberlite

Here you can know more about Rhyolite and Kimberlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyolite and Kimberlite consists of mineral content and compound content. The mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz and mineral content of Kimberlite includes Garnet, Olivine, Phlogopite, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Rhyolite vs Kimberlite, 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, Kimberlite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors. Appearance of Rhyolite is Banded and that of Kimberlite is Dull and Banded. Properties of rock is another aspect for Rhyolite vs Kimberlite. Hardness of Rhyolite and Kimberlite is 6-7. The types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. whereas types of Kimberlite are Basaltic Kimberlites and Micaceous Kimberlites. 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 Kimberlite is white.
