Fretzdorff, M. Paterne, P. Stoffers, E. Ivanova] Abstract.: The explosive activity of Réunion volcanoes since approximately 260ka is investigated through detailed sedimentologic, isotopic, and geochemical analyses of three deep-sea marine cores. Twenty-four eruptions from Piton des Neiges and one from Piton de la Fournaise are identified. The marine stratigraphic record of ash layers is undisturbed, whereas corresponding tephra deposits on land may have disappeared or have been disturbed through erosion and volcano-tectonic processes. Consequently, the new data presented herein may be regarded as a reference sequence of the main explosive events of Réunion. In addition, the chronology based on δ18O stratigraphy offers continuous time constraints with respect to other isotopic methods used for dating lavas. Explosive events were more frequent during the period 180-150ka. The comparison of major element composition and chronologic data between known explosive deposits on land and marine ash layers allows us to propose correlations between marine and land data. However, most of the marine ash layers do not yet have a recognized subaerial counterpart. For the main explosive events known on land, we propose the following succession: Sainte Suzanne formations, ≥257-240ka; Dalle Soudée Formation, 218ka; Salazie formations, two groups at 165-168ka and 80-102ka; Saint Gilles formations, 175ka; Saint Louis formations, 158-161ka; and Saint Pierre formations, 165-166ka.
