Summary: Leg 115 recovered basaltic rocks from four sites along the ancient trail of the Reunion hotspot. The age of volcanism increases to the N and records the motion of India away from the hotspot through the Tertiary. Activity began with the eruption of the Deccan flood basalts at the K/T boundary. The Reunion hotspot has been stationary with respect to other Atlantic and Indian ocean hotspots through the Tertiary. The geochemical compositions of the drilled basalts differ according to the relative contributions of magmas from hotspot and MORB mantle sources.
