Glass and bulk rock magma composition of Deception Island’s pre-, post- and syn-caldera (OCTF) juvenile fragments. (A) Total Alkali vs. Silica diagram (TAS)53. Major elements are normalized to 100% (anhydrous) with Fe distributed between FeO and Fe2O3 following ref.54. The grey dashed line discriminates between the alkaline-subalkaline fields55. (B) Major element vs. SiO2 content Harker Diagrams. Major element compositions have been normalized to 100% in anhydrous base with Fe as FeOt. See Supplementary Information File 2 for details on composition and exact latitude-longitude coordinates of the rock samples.
