Tatanan
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.
Schist kawangun dening metamorphism dinamis ing dhuwur Suhu lan tekanan sing aligns pari-parian saka mica, hornblende lan mineral elongated liyane menyang lapisan lancip.
