tatanan
nephelinite 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.
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.
