Fig. 2: Size-segregated concentrations (not ash-corrected) of elements in particulate matter measured in the magmatic and laze plumes, in order of volatility.

Note the different emanation coefficient scales on a and b. a Refractory (ε < 0.001%) elements in the magmatic plume, with emanation coefficients (ε; triangle and circle markers with white fill) calculated for the magmatic plume for the two non-saturated ground-based samples also shown. ε error bars represent the propagated errors (see Supplementary Note 7; ε data in Supplementary Data 1 Table S10). b Volatile elements (ε > 0.001%) in the magmatic plume, with emanation coefficients. c Refractory elements in the laze plume. d Volatile elements in the laze plume. All elements were measured by ICP-MS or ICP-OES except where indicated; IC ion chromatography, D cutoff diameter as defined in methods, BDL below detection limits (of either the instrument, or below filter blanks). Elements are ordered by average emanation coefficient, increasing from left to right.
