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.
Wangun blueschist amarga metamorphism saka basalt lan rocks liyane karo komposisi padha ing tekanan dhuwur lan kurang Suhu lan kira-kira cocog kanggo ambane saka 15 kanggo 30 kilometer lan 200 kanggo 500 ° c.
