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 novaculite nalika microcrystals silikon dioksida tuwuh ing endapan alus sing dadi watu gamping utawa kapur. tatanan novaculite bisa dadi salah siji saka asal kimia utawa biologi.
