Formasi Websterite lan Batubara

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

Wangun coal saka klempakan saka lebu tetanduran ing lingkungan rawa kang wis kakubur sedimen kayata lendhut utawa wedhi lan banjur compacted kanggo mbentuk coal.
