anorthosite punika phaneritic, intrusive rock igneous kang ditondoi dening predominance saka plagioclase Feldspar kang meh 90-100%, lan komponèn mafic tithik.
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.
