trachyte iku sawijining rock vulkanik igneous karo aphanitic kanggo tektur porphyritic. iku padha karo vulkanik saka syenite rock lan formulir minangka asil diferensiasi magmatic.
nalika Feldspar alkali sing dijupuk saka granit, iku diganti kanggo granitoid lan mengko, dadi tonalite karo quartz minangka mineral utama.
