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.
borolanites sing kawangun amarga aktivitas igneous alkalin lan umumé kawangun ing wilayah dharatan crustal nglukis utawa ing zona subduksi cordilleran.
