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.
Shoshonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Rhyolite vs Shoshonite 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 Shoshonite Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. Shoshonite is a basaltic rock, properly a potassic trachyandesite, composed of olivine, augite and plagioclase phenocrysts in a groundmass with calcic plagioclase and sanidine and some dark-colored volcanic glass. 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 Shoshonite information and Rhyolite vs Shoshonite characteristics in the upcoming sections.

Rhyolite vs Shoshonite 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 Shoshonite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Rhyolite and Properties of Shoshonite. Learn more about Rhyolite vs Shoshonite in the next section. The interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens whereas the interior uses of Shoshonite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Rhyolite and Shoshonite, 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 Shoshonite include As dimension stone, Cobblestones, Rail track ballast, Roadstone.

More about Rhyolite and Shoshonite

Here you can know more about Rhyolite and Shoshonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Rhyolite and Shoshonite consists of mineral content and compound content. The mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz and mineral content of Shoshonite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Rhyolite vs Shoshonite, 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, Shoshonite is available in brown- black, dark brown colors. Appearance of Rhyolite is Banded and that of Shoshonite is Dull. Properties of rock is another aspect for Rhyolite vs Shoshonite. The hardness of Rhyolite is 6-7 and that of Shoshonite is 6. The types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. whereas types of Shoshonite are Not Available.
