The volcanic stage of the 2.7-Ga Abitibi greenstone belt, Canada, is dominated by bimodal arc magma series and komatiite-basalt sequences. The latter represents an aerially extensive oceanic plateau erupted from an anomalously hot super-plume. Komatiites define a linear array of Nb/Th vs. Nb/U, extending from Nb/Th=8-20, and Nb/U=26-58, whereas basalts plot on a separate, but overlapping ...

Transect C, however, images the deepest part of the graben where the underlying crystalline basement is at ~16 km depth, and is associated with a large gravity low of ~−30 mGal. Toward the shelf-edge, the gravity anomaly gently rises to a peak of 45 mGal and corresponds to a zone where the crystalline basement elevates to a depth of ~6 km.
