Fig. 2

δ44/40Ca of bulk zeolites versus approximate burial depth in the Berufjörður–Breiðdalur region64. The orange line shows the average value for all basalts analyzed here and by Jacobson et al. (2015), with the width encompassing the standard deviation (−1.05 ± 0.06‰, 2σSD, n = 11). Error bars show external reproducibility (±0.05‰, 2σSD).
