tatanan
dacitic magma wis kawangun dening subduksi saka lemah ndhuwur enom laut ing piring Continental felsic nglukis. luwih, ing satunggalipun saperangan wis hydrothermally ngrubah minangka quartz lan sodium sing ditambahake.
Wangun coal saka klempakan saka lebu tetanduran ing lingkungan rawa kang wis kakubur sedimen kayata lendhut utawa wedhi lan banjur compacted kanggo mbentuk coal.
