Alkalic, or alkali, syenytes are a special group of rocks that are differentiated from other syenites by the fact that they contain a feldspathoid mineral, such as sodalite, leucite, or nepheline. They also contain significantly less quartz than other syenites. Relatively rare on a global scale, one of the best examples of an alkalic syenite can be found at Mont St. Hilaire in Quebec, Canada.  2, fiche 1, Anglais, - alkali%20syenite

Two groups of syenites have long been distinguished, the "alkali syenites" and the "alkali-lime syenites", or "orthosyenites".  5, fiche 1, Anglais, - alkali%20syenite
