Book excerpt: This study documents alkaline rock occurrences in British Columbia; describes their petrography, geochemistry, economic geology, and field relationships; and determines the timing and tectonic controls of emplacement, providing a basis for future, detailed studies. Work was begun in 1984 and included field mapping during the summers of 1984, 1985, and 1986. All the carbonatite-syenite localities (with the exception of the Wicheeda Lake and Mount Bisson showings) and a large number of the diatreme breccias were mapped and sampled.
