“The sodalite syenite is worthy of note as the source of an interesting minerals assemblage. Small cavities rarely exceeding 5 cm in diameter between the sodalite and feldspar crystals yield a wide variety of micro minerals. Sodium silicates are abundant; various sulfides and carbonates are also present in small quantities”.*
“Sodalite may be present in excellent crystals lining the cavities. The sodalite syenite can contain local concentrations of cancrinite, nepheline and aegirine. It is a pale gray to beige colored rock by comparison with the more common nepheline syenite, which is uniformly dark gray. Coarse grained sodalite syenite is characterized by sodalite crystals with hexagonal outline set in a finer grained ground mass; such syenite is locally pale to deep blue”.*
