From: Basaltic Plinian eruptions at Las Sierras-Masaya volcano driven by cool storage of crystal-rich magmas

Fig. 4

Panels are presented in order of increasing incompatibility in plagioclase, from (a) Zr vs Sr, (b) Zr vs Ba to (c) Zr vs La. The melt differentiation trend for the FL eruption is modelled using the most primitive MI as the starting composition. Each square along the fractional crystallisation path represents an increase in crystal fraction of 0.1. Trace element concentrations in plagioclase-hosted MI and matrix glass of the MTL eruption are also presented. Literature data from samples of post-caldera activity20,23 and the MT-TIL eruption23 are also shown. Literature data from samples of the MTL eruption23 are highlighted by the open squares and triangles with the red outline. Grey error bars represent the analytical uncertainty (2σ) for samples from this study.
