tatanan
peridotites bisa kawangun ing rong cara: minangka rocks lapisan kawangun sak accretion lan diferensiasi saka bumi utawa minangka rocks cumulate kawangun dening udan saka olivine lan pyroxenes saka magmas basaltic.
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.
