nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
migmatites mbentuk dening suhu dhuwur metamorphism regional lan termal saka rocks protolith ngendi rocks nyawiji sebagian amarga suhu dhuwur.
