Syenite is not a common rock, some of the more important occurrences being in new-england, arkansas, montana, new-york(syenite gneiss), switzerland, germany, and norway
Extremely iron-rich olivine is rare, but is present in some nepheline syenite. Other minerals common in minor amounts include sodium-rich pyroxene, biotite, titanite, zircon, iron oxides, apatite, fluorite, melanite garnet, and zircon. Cancrinite occurs in several nepheline-syenites.
