Huh. The timing of the formation overlies that of the Deccan traps and lacadive ridge, which runs right through the geoid low. While the current model for the Deccan traps proposes the reunion hotspot, it would be interesting if anyone does further integrative research to see if the the two phenomena are related

I read into this a little more. there are theories about chicxulub meteor causing an antipodal eruption in that vicinity. Much uncertainty about plate tectonics for further study. https://news.berkeley.edu/2015/04/30/did-dinosaur-killing-asteroid-trigger-largest-lava-flows-on-earth/

I've been reading that the k-Pg is found in the Deccan traps, suggesting that the eruptions had already been going on at the time of the chicxulub impact. So, no consensus on a relationship there. But the geoid low being related is an interesting suggestion!
