... model of emplacement of the rocks was offered. We propose a model of origin of the Rajmahal Traps of northeastern India, the 85°E Ridge, and Afanasy Nikitin Seamount as the trace of the hotspot that now lies beneath the Crozet Islands in the southern Indian Ocean. This reconstruction places...

... anomaly due to the incipient Kerguelen plume pre-dated the Rajmahal Traps, emplaced at about 118 Ma, by ∼6 million years. An early Kerguelen hot-spot position north of Elan Bank, with subsequent southward migration, is also supported by palaeomagnetic data and mantle convection models. The Wallaby Plateau...

... in a location of the Kerguelen hotspot distinct from and south of the Rajmahal Traps for this time interval. Between 115 and 105 Ma, our model locates the hotspot underneath the southern Kerguelen Plateau, which is compatible with an age estimate of this part of the plateau of 115-95 Ma. Our model suggests...
