Abstract

Leg 115 of the Ocean Drilling Program recovered basaltic rocks from four sites along the ancient trail of the Réunion hotspot. The age of volcanism, determined from biostratigraphic data at the four sites, increases to the north and records the motion of India away from the Réunion hotspot through Tertiary time. Hotspot activity began with the eruption of the Deccan flood basalt flows at the time of the Cretaceous/Tertiary boundary. The Réunion hotspot has been stationary with respect to other hotspots in the Atlantic and Indian Ocean basins through Tertiary time. The geochemical compositions of the drilled basalts differ according to the relative contributions of magmas from hotspot and MORB mantle sources.
