(Table 1) Chemical and isotopic analyses of Rajmahal Traps and Ninetyeast Ridge volcanics

DOI

The hypothesis that hotspots are the sources of many continental flood basalts is evaluated geochemically for the proposed Rajmahal Traps-Ninetyeast Ridge-Kerguelen hotspot system. It appears that the Kerguelen hotspot did not directly feed Rajmahal magmas, although it may have provided a source of heat for Rajmahal activity.
