Formasi Nepheline Syenite lan Tonalite


Formasi Tonalite lan Nepheline Syenite


Tatanan

tatanan
syenites nepheline sing kawangun amarga aktivitas igneous alkalin lan umumé kawangun ing wilayah dharatan crustal nglukis utawa ing zona subduksi cordilleran.   
nalika Feldspar alkali sing dijupuk saka granit, iku diganti kanggo granitoid lan mengko, dadi tonalite karo quartz minangka mineral utama.
