Extended Data Fig. 3: Mineral compositions.
From: Rapid shifting of a deep magmatic source at Fagradalsfjall volcano, Iceland
The range in a. Fo content of olivine, b. Mg# of clinopyroxene, c. An content of plagioclase and, d. Cr# of spinel. Core and rim compositions are depicted as circles and diamonds, respectively. Red bar shows the mineral compositions in equilibrium with the most primitive melt inclusions, pink bars are equilibrium compositions with a whole rock-like liquid, whereas purple bars indicate mineral compositions in equilibrium with tephra glass sampled in March. Numbers in each corner state the number of point analyses in minerals. Variation diagrams showing the NiO vs Fo content of olivine e., Al2O3/TiO2 vs Mg# clinopyroxene f., FeO content vs An content of plagioclase g. and Mg# vs Cr# in spinel macrocrysts h. Kernel density estimates on the top axis produced using a bandwidth of 0.2 show the relative probability of mineral compositions, determining the main compositional populations in each mineral. Representative error bars are included on all panels and include external 2σ error.
