It is speculated that the Sodalite bearing syenite rocks originated from one of several alkaline intrusive bodies in Ontario, north of Lake Superior and then were transported south during continental glaciation movement.  The rocks are igneous intrusive rocks called syenite.  The fluorescent mineral is sodalite.  Sodalite is one of several feldspathoid minerals that form in sodium-rich magmas that contain so little silicon and aluminum that quartz and feldspar are absent making it somewhat rare compared to granite and other silica-rich igneous rocks and feldspathoid-bearing syenites rocks.
