Dacite vs Obsidian 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 Dacite and Obsidian Reserves. Dacite is a volcanic igneous rock which is rintermediate in composition between andesite and rhyolite. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. It is produced when felsic lava extruded from a volcano cools rapidly with minimum crystal growth. 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 Dacite vs Obsidian information and Dacite vs Obsidian characteristics in the upcoming sections.
