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.
amarga kanggo ngganti ing kondisi lingkungan, rocks sing digawe panas lan pressurized jero nang permukaan bumi. pseudotachylite kawangun saka panas nemen disebabake magma utawa dening tabrakan kuat lan gesekan lempeng tektonik.
