... derivation, ΔNb is calculated to search for a deep-mantle signature (ΔNb > 0). The signature of the Réunion hot spot, from ∼65–0 Ma, is seen in the Deccan Traps, India, lavas from the Mascarene Plateau, and Réunion Island. The signature of the Kerguélen plume is detected in rocks from Kerguélen Island...

We note that alternative models have suggested that the Kerguelen plume-head composition could be distinct from that of the plume tail, which can be represented by the composition of the Cenozoic Kerguelen Archipelago and Heard Island basalts and the composition...

... that some volcanic activity is delayed by a magma-storage mechanism somewhere in the lithosphere. For example, the oldest rocks on Heard Island on the Kerguelen Ridge are 40 m.y. old, but there has been some activity in historic times. I assume that the entire Kerguelen Ridge is a hot-spot feature...

This may be related to the Kerguelen plume activity, which affected the area a bit later. The reflective top of the exhumation domain represents the convex-up fault (Figs 3 & 8 ). This fault...
