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.
Trachyte is an igneous volcanic rock with an aphanitic to porphyritic texture. It is the volcanic equivalent of syenite rock and forms as a result of magmatic differentiation.

Rhyolite vs Trachyte 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 Trachyte Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. Trachyte is a grey fine-grained volcanic rock which mainly consists of alkali feldspar. 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 Trachyte information and Rhyolite vs Trachyte characteristics in the upcoming sections.

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

More about Rhyolite and Trachyte
