S. Ingle, J. S. Scoates, D. Weis, Gerhard Brügmann & R. W. Kent
Rifting between eastern India and western Australia in the Early Cretaceous (similar to 140-133 Ma) resulted in the formation of the eastern Indian Ocean. Tholeiitic flood basalts erupted on the southwestern margin of Australia (Bunbury basalts at similar to 132 and similar to 123 Ma) and the eastern margin of India (Rajmahal Traps at similar to 118 Ma) shortly after this time, while the Kerguelen Plateau began to form in the nascent ocean basin (similar...
