Abstract
The dataset is consistent with the lower Dalradian Supergroup being sourced from the eastern Laurentian (Labrador region) and/or possibly western Baltica blocks. These data indicate that the basins were flanked to the west by ca. 1.8Â Ga Makkovikian-Ketilidian (Rhinnian) igneous basement and to the east by 1.0Â Ga Grenvillian-Sveconorwegian basement. This interpretation, combined with the similarities with other penecontemporaneous Laurentian rift-basin fills, indicates that the Dalradian Supergroup is not allochthonous or exotic to the Laurentian continental block.
