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.
Wangun eclogite saka tekanan dhuwur metamorphism saka batuan beku mafic utamané, basalt utawa gabbro minangka plunges menyang lapisan ing zona subduksi.
