“…The most recent published work on the gravity structure of the island of La Réunion is Malengreau et al (1999), but new data has since been collected (Lambert, unpublished data, 2003;Lénat et al, unpublished data, 2003;Levieux unpublished data, 2004), allowing us to strengthen the interpretation. The Bouguer anomaly map of La Réunion is dominated by two large positive anomalies: one centered on Piton des Neiges volcano and the other on the eastern coast.…”

High-resolution Malengreau et al (1999), Charvis et al (1999, Gallart et al (1999), and Lénat et al (2001). Les Alizés volcano has been destroyed and cannot be observed on land; its inferred previous shape is shown.…”

“…2.1 Ma to 12 ka (McDougall 1971;Deniel et al 1992). An ancient volcano underlying the Piton de la Fournaise was proposed by Malengreau et al (1999) based on gravimetric anomalies and by a gabbroic and cumulate complex identified between 1 and 3 km below sea level (bsl) with deep geothermal exploration drill hole in the Grand Brûlé area (Fig. 2c), in the eastern part of the island (Rançon et al 1989).…”

“…On the other hand, relative positive anomalies such as the signal in the middle of the caldera and spatially related with volcanic edifices (Fig. 3) are interpreted as being produced by dense intrusive bodies (e.g., Rymer and Brown, 1986;Malengreau et al, 1999;Gudmundsson and Högnadóttir, 2007), due to the crystallization of the densest mineralogical phases during magma ascent and emplacement. Finally, positive anomalies outside of the caldera are interpreted as the response to the uplift of dense Paleozoic basement.…”
