Rhyolite vs Basaltic Trachyandesite


Basaltic Trachyandesite vs Rhyolite


Definition

Definition
Rhyolite is a fine-grained igneous rock which is rich in silica   
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

Rhyolite vs Basaltic Trachyandesite 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 Basaltic Trachyandesite Reserves. Rhyolite is a fine-grained igneous rock which is rich in silica. Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface. 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 Basaltic Trachyandesite information and Rhyolite vs Basaltic Trachyandesite characteristics in the upcoming sections.
