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 blueschist amarga metamorphism saka basalt lan rocks liyane karo komposisi padha ing tekanan dhuwur lan kurang Suhu lan kira-kira cocog kanggo ambane saka 15 kanggo 30 kilometer lan 200 kanggo 500 ° c.
