Some rocks according to their use or texture are classified into different types. Know more about Basalt Texture and Skarn Texture. Types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite whereas the types of Skarn are Endoskarns.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.

These are images created by removing part of a rock surface by incising, picking, carving or abrading, as a form of rock art. Basalt was used to create petroglyphs whereas Skarn was not used to create petroglyphs.
