Formation

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Serpentinite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Rhyolite vs Serpentinite 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 Serpentinite Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.. 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 Serpentinite information and Rhyolite vs Serpentinite characteristics in the upcoming sections.

Rhyolite vs Serpentinite 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 Serpentinite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhyolite and Properties of Serpentinite. Learn more about Rhyolite vs Serpentinite in the next section. The interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Serpentinite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Rhyolite and Serpentinite, 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 Serpentinite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Rhyolite and Serpentinite

Here you can know more about Rhyolite and Serpentinite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyolite and Serpentinite consists of mineral content and compound content. The mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz and mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Igneous Rocks. When we have to compare Rhyolite vs Serpentinite, 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, Serpentinite is available in black, brown, green, grey, white colors. Appearance of Rhyolite is Banded and that of Serpentinite is Rough and Dull. Properties of rock is another aspect for Rhyolite vs Serpentinite. The hardness of Rhyolite is 6-7 and that of Serpentinite is 3-5. The types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. whereas types of Serpentinite are Jadeitite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Rhyolite is while that of Serpentinite is white, greenish white or grey. The specific heat capacity of Rhyolite is 0.71 kJ/Kg K and that of Serpentinite is 0.95 kJ/Kg K. 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 Serpentinite is heat resistant.
