tatanan
nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
nalika Feldspar alkali sing dijupuk saka granit, iku diganti kanggo granitoid lan mengko, dadi tonalite karo quartz minangka mineral utama.
