Tatanan

tatanan
rhyodacite punika, hard rock nggoleki-grained kang jinis metasomatite, ateges ngrubah basalt. iku formulir karo utawa tanpa crystallization, salah siji ngisor permukaan minangka rocks intrusive utawa ing lumahing minangka rocks extrusive.   
phonolite sing kawangun amarga aktivitas igneous alkalin lan umumé kawangun ing wilayah crustal Continental nglukis utawa ing zona subduksi cordilleran.
