tatanan
rhyolite punika rock extrusive felsic lan amarga isi silika dhuwur, rhyolite lahar banget viscous lan padha vulkanik granit.
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.
