Obsidian vs Pyroxenite

Obsidian vs Pyroxenite 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 Obsidian and Pyroxenite Reserves. 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. Pyroxenite is a dark, greenish, granular intrusive igneous rock consisting mainly of pyroxenes and olivine. 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 Obsidian vs Pyroxenite information and Obsidian vs Pyroxenite characteristics in the upcoming sections.
