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.
websterite bisa kawangun minangka cumulates ing intrusions ultramafic dening klempakan saka kristal pyroxene ing dasar ing kamar lahar.
