Schist kawangun dening metamorphism dinamis ing dhuwur Suhu lan tekanan sing aligns pari-parian saka mica, hornblende lan mineral elongated liyane menyang lapisan lancip.
Wangun coal saka klempakan saka lebu tetanduran ing lingkungan rawa kang wis kakubur sedimen kayata lendhut utawa wedhi lan banjur compacted kanggo mbentuk coal.
