Fig. 7From: The element-release mechanisms of two pyrite-bearing siliciclastic rocks from the North German Basin at temperatures up to 90 °C under oxic and anoxic conditionsSimulated (lines) and measured (dots) Fe concentrations released over time during oxic experiments from a Hettangian sandstone and b Sinemurian siltstone. The normalized root mean square errors for each temperature are shown in Fig. 6 Back to article page
