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.
rocks adakite sing kawangun nalika cairan hydrous sing dirilis saka mineral sing break mudhun ing basalt metamorfosis, lan munggah menyang lapisan, banjur padha salat leleh sebagean.
