Types of Rhyolite and Basaltic Trachyandesite

Some rocks according to their use or texture are classified into different types. Know more about Rhyolite Texture and Basaltic Trachyandesite Texture. Types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks. whereas the types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite.During historic times, some rocks depending on their hardness were used to create Pictographs and Petroglyphs. Rocks which are hard were generally not used. Pictographs are paintings or drawings that have been placed or created on the surface of rock. Rhyolite was not used to create pictographs whereas Basaltic Trachyandesite is used to create pictographs. Petroglyph is an image which is carved into a rock. These are images created by removing part of a rock surface by incising, picking, carving or abrading, as a form of rock art. Rhyolite was not used to create petroglyphs whereas Basaltic Trachyandesite was used to create petroglyphs.
