The 575-560 Ma Seiland Igneous Province is an intrusive suite of mafic and ultramafic rocks, occasional mozonites and diorites, and, carbonatite and (nepheline)-syenite alkaline dikes on the northwest margin of Baltica that have a contested geo-tectonic origin. The carbonatite and alkaline magmas we...
