The Canadian nepheline syenite industry began in 1932 when claims were staked on Blue Mountain near Peterborough, Ontario, where it is still produced. nepheline syenite, medium- to coarse-grained intrusive igneous rock, a member of the alkali-syenite group ( see syenite) that consists largely of feldspar and nepheline. The basic difference between these is in the amount and types of feldspars present. The bulk of the pluton (~ 95% of the exposed area) consists of three intrusive series, including (in order of emplacement): (1) nepheline and nosean syenites, (2) a differentiated series of urtites and feldspathoid syenites, and (3) eudialyte lujavrites (trachytic meso- to melanocratic nepheline syenites). The feldspathoids are a group of tectosilicate minerals which resemble feldspars but have a different structure and much lower silica content.
