Nepheline syenite xenoliths in nordmarkite intrudes larvikite close to Romsdal, southwest of the Lake Mykle. A strongly altered nepheline syenite dyke, with marked mineralogical simi­larity to the xenoliths, intrudes larvikite close to the Romsdal locality (Andersen & Sørensen 1993).

The coordinates are approximate and needs to be confirmed.
