tatanan
aplites kagungane intrusive batuan beku kang biasane quart lan Feldspar alkali lan sing kawangun saka ampas eutectic cairan granitic lan makili produk crystallization final saka magma.
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.
