Lead isotope plots. a 207Pb/204Pb versus 206Pb/204Pb plot showing the composition of the magnetic fractions separated from quenched lava samples, the bulk compositions of the pipe, the bucket and unquenched lavas. b Temporal evolution of 206Pb/204Pb in Piton de la Fournaise lavas. Unradiogenic Pb spikes in October 1977, July 2001, August 2003 and April 2007 result from the contamination of quenched samples
