obahe bumi bisa nimbulaké rocks dadi salah siji rumiyin disarèkaké utawa squeezed lan Empu rocks sing digawe panas lan sijine ing meksa gedhe.

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.
