Reductively leached Sr isotope compositions of the Swiss iron oolites from Herznach, Windgällen and Erzegg compared to the Jurassic seawater Sr isotope curve (with a 95% confidence interval; Wierzbowski et al., 2017). Leached Sr isotopes are more radiogenic than contemporary seawater due to metamorphic overprint (Sect. 5.2). Error bars on ages reflect available age constraints (see Tables 1 and 3). Ages after Gradstein et al. (2012). Aal. Aalenian, Bj. Bajocian, Bt. Bathonian, Cl. Callovian, Oxf. Oxfordian, Kimm. Kimmeridgian, Tith. Tithonian, Berri. Berriasian
