Popis:	Pillow lavas containing an eclogitic mineral assemblage, locally with glaucophane/crossite, are described from the Tsakkok Lens within the Seve Nappes, north-central Scandinavian Caledonides. Critical primary relationships to the host metasedimentary rocks which are dominated by marble and quartz-garnet-phengite schist are preserved. It is argued that these clastic rocks, and the ongoing igneous activity in the Tsakkok Lens, are late Precambrian to Cambrian in age and that these rocks were deposited/emplaced along the outermost part of a continental margin related to the continent Baltica.
