Fig. 3: δ44/40Ca versus Sr/Ca for primary minerals, bulk basalt, calcite, and zeolites.

From: Large calcium isotope fractionations by zeolite minerals from Iceland

Fig. 3

a Ca isotope measurements of all samples. Symbol size is larger than the external reproducibility (±0.05‰, 2σSD). b Inset from panel (a) includes basalt from the Berufjörður–Breiðdalur region (dark blue triangles), as well as basalt from previous studies (light blue triangles)21.
