Microscopie examination and comparison of chemical analyses have indicated the possibility of the common origin of the rocks of the thesis area and that of Mount Royal. However, final proof was obtained using the Barth system of petrographic calculations. These show the tinguaite to be a differentiate of the nepheline-syenite, while the dike rocks have been derived from the original essexite magma.
