5 Tatanan
5.1 tatanan
gneiss punika bahan dhuwur metamorphic rock IE wis ngalami luwih Suhu lan tekanan saka Schist. iku kawangun dening metamorfosis saka wangun gneiss saka rock vulkanik, krikel utawa granitie.
websterite bisa kawangun minangka cumulates ing intrusions ultramafic dening klempakan saka kristal pyroxene ing dasar ing kamar lahar.
