Geochemical analyses of selected glass shards. (a) total Alkali Silica (TAS42) plot of glass composition from the Dead Sea (DS_137.51, DS_137.495, DS_137.51_1cm) compared to proximal deposits of the fall, lower, intermediate and upper flow deposits18,19 as well as distal records22,24,25,28. (b–d) Major element bi-plots showing the glass composition of the shards from the Dead Sea correlate well with proximal and distal CI tephra layers rather than pre-CI deposits. (e,f) Trace element bi-plots showing selected compositions of the Dead Sea shards and compare well to the composition of the proximal CI19, particularly Upper Flow/co-PDC deposits, rather than the pre-CI eruptions28,43. Error bars are 2 standard deviations calculated using replica analysis of the MPI-DING StHs6/80-G glass standard44 for both major and trace element measurements
