Lead isotopes behavior in the fumarolic environment of the Piton de la Fournaise volcano (Reunion Island)
The recent activity of the Piton de la Fournaise volcano offers a rare opportunity to address the issue of Pb isotope behavior in volcanic fumaroles, as the composition of the degassing source is accurately and precisely known. Gas sublimates formed between 2007 and 2011 at temperature ranging from 400 to ca. 100 C include Na–K sulfate (aphthitalite), Ca–Cu sulfate (e.g., gypsum), Na sulfate (t...

متن کاملAutomated identification, location, and volume estimation of rockfalls at Piton de la Fournaise volcano
Since the collapse of the Dolomieu crater floor at Piton de la Fournaise Volcano (la Réunion) in 2007, hundreds of seismic signals generated by rockfalls have been recorded daily at the Observatoire Volcanologique du Piton de la Fournaise (OVPF). To study rockfall activity over a long period of time, automated methods are required to process the available continuous seismic records. We present ...
متن کاملCrustal Contamination of Kilauea Volcano Magmas Revealed by Oxygen Isotope Analyses of Glass and Olivine from Puu Oo Eruption Lavas
Oceanic island basalts have a large range in dO values (4·5– INTRODUCTION 7·5‰) compared with the assumed primordial mantle values A 1996 conference on ‘shallow level processes in ocean (5·5–6·0‰) and with mid-ocean ridge basalts (5·7 ± 0·2‰). island magmatism’ drew attention to the controversy that Some Hawaiian tholeiitic basalts have low O values (4·6–5·2‰), is developing on the possible ext...
متن کاملFish community structure in relation to environmental variation in coastal volcanic habitats
This study constitutes one of the few works conducted on the colonization of recent lava flows by fish communities in coral reef environment. It attempted to describe themechanisms of colonization and environmental variables influencing the structure of communities on the lava flows of the Piton de la Fournaise volcano at Reunion Island. It also proposed somehypotheses on themechanisms of selec...
