a Porosity versus time for quenched lava fragments collected during the 2014 and 2015 eruptive events at Piton de La Fournaise; b BSE (Back-Scattered Electron Imaging mode) image of a quenched sample from the July 2015 lava flow, in which: V = vesicles; C = mesocrystals of plagioclase and clinopyroxene; G = glass plus microcrystals of plagiolase, clinopyroxene and olivine; c zoom of the area identified in (b) by the red rectangle, where P = plagioclase and C = clinopyroxene
