1 Tatanan
1.1 tatanan
dacitic magma wis kawangun dening subduksi saka lemah ndhuwur enom laut ing piring Continental felsic nglukis. luwih, ing satunggalipun saperangan wis hydrothermally ngrubah minangka quartz lan sodium sing ditambahake.
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.
