Greater Kerguelen large igneous province reveals no role for Kerguelen mantle plume in the continental breakup of eastern Gondwana

Greater Kerguelen large igneous province reveals no role for Kerguelen mantle plume in the continental breakup of eastern Gondwana

The link between mantle plumes and continental breakup remain a topic of debate. Here, a new 40 Ar/ 39 Ar age of 135.9 ± 1.2 Ma (2σ) and previous ages from the Bunbury Basalt – lava flows that are part of the Greater Kerguelen large igneous province (LIP) – reveal that >80% of magmatism in the so...
