Abstract
Previous studies showed that the Rajmahal‐Sylhet‐Bengal (RSB) flood basalt province (117 ± 2 Ma) in eastern India was spatially close to the active Kerguelen hotspot about 118 Ma ago. Yet, it could not be unequivocally correlated to this hotspot due to wide variation in isotopic compositions of both the RSB and Kerguelen plateau basalts. However, we report Sr‐Nd‐Pb isotopic compositions (87Sr/86Sri: 0.70535 to 0.70561; εNd(T): −2.6 to −3.2; 206Pb/204Pbi: 17.88 to 18.07) of a co‐eval (116 ± 2 Ma) Group II kimberlite from this flood basalt province that is identical to recently identified pristine Kerguelen plume basalts from the Kerguelen Plateau/Archipelago and Broken Ridge. This suggests that the Kerguelen hotspot could indeed be responsible for the ∼117 Ma magmatic activity in Eastern India.
