Volcanic types are intricately connected with the types of magma, lava and volcanic rock (also known as igneous rocks) composition which shape the volcano and the surrounding area. Minerals form in igneous rocks when molten magma or lava solidifies. The densest minerals, ferromagnesian silicates, form at the highest temperatures, whereas less dense minerals form when the magma cools down. Mineral types forming in molten rock often grow unrestricted to a very large size, and can have a fine crystal form. At most basic, there are eight basic types of lava, which reflect the main types of volcanic rock which the lava is composed of. These types are:
• Basalt
• Andesite
• Dacite
• Rhyolite
• Carbonatite
• Natrocarbonatite
• Komatite
