Early Cretaceous Alkaline Magmatism of East Antarctica: Peculiarities, Conditions of Formation, and Relationship with the Kerguelen Plume

Distribution of oceanic crust in the Enderby Basin offshore East Antarctica

“…During the early part of this drift phase, the dispersal was accompanied by excess magmatism related to the arrival of the Kerguelen mantle plume. Remnants of volcanism from this event are known onshore in the Prydz Bay region, from the western flank of the Lambert Rift (Coffin et al 2002;Sushchevskaya et al 2018), and from the Rajmahal flood basalts erupted onshore between 112 and 118 Ma in the conjugate parts of India (e.g. Mahoney et al 1983;Kent et al 2002).…”
