Fig. 4: Viscometry and scaling analysis pertaining to ore melt separation from parent magma body.
From: Genetic model of the El Laco magnetite-apatite deposits by extrusion of iron-rich melt
a Viscometry results (symbols) with fitted model (lines) for rhyolite (green), andesite (purple), Fe-clinopyroxene (pink), and magnetite (amber) compositions (see Table 1 and Supplementary Table 1); b regime diagram of three-phase flow between Si-rich melt (ϕmSi), Fe-rich melt (ϕmFe), and phenocryst (ϕxtl) phases transitioning from droplet settling at high melt content to melt percolation at intermediate to high crystallinity. c–e Results of the scaling analysis giving the characteristic speed of phase buoyancy-driven magma/mush convection (c), the speed of Fe-rich melt segregation from the silicate magma/mush (d), and the characteristic length scale of Fe-rich melt segregation (e).
