Fig. 14From: Pre-eruption magmatic processes and magma plumbing system at Hachijo-Nishiyama volcano, Izu–Bonin arc, JapanCalculated variations in the densities of the melt and plagioclase with pressure. The dry melt composition is represented by the groundmass composition of sample #7-4 (Additional file 1: Table S1). The densities of the melt and plagioclase were calculated using the models of Iacovino and Till (2019) and Berman (1988), respectivelyBack to article page
