Description
Additional file 1 provides major-element compositions of matrix glass and biotite from thin ash units of the Youngest Toba Tuff (YTT), a 74,000-year-old super-eruption. The data, determined by Electron Probe Microanalysis (EPMA), includes analyses of international glass standards (GSD-2g, BCR-2ga, BHVO-2g) used to evaluate analytical uncertainty. It was authored by Gabriela Nogo Retnaningtyas Bunga Naen and last updated on 2026-04 16.
Use Cases
Calibrate analytical methods based on the included international glass standard data.
Analyze geochemical variations in the Youngest Toba Tuff based on major-element compositions.
Investigate eruptive processes and magma chamber dynamics based on glass and biotite compositions.
Assess analytical uncertainty in EPMA measurements based on the standard analyses.
Strengths
Includes analyses of three international glass standards (GSD-2g, BCR-2ga, BHVO-2g) for uncertainty evaluation.
