Mössbauer spectra and fit subspectra for 14d-incubated (a) pH14d 8.4, (b) pH14d 3.7, (c) pH14d 3.1 and (d) pH14d 1.8 Adirondack basalt simulant collected at RT [subspectral areas in % are for Ol = olivine; Total Gl = total glass, a sum of 2D1 and 2D2 doublets (Table EA-2), Total Sme = total smectite, and Total Alt Gl = total altered glass, a sum of 3D2 and 2D4 doublets (Table EA-2)]. TC = total counts, BC = baseline counts.
