Fig. 1From: 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 conditionsData taken from Müller et al. (2017)Mass fractions (mg/g sediment) and phase associations of mobile elements in the sampled rocks, as determined by sequential extraction with 1 g of rock and 30 mL of solvent. The phases are X, exchangeable; A, acid-soluble; R, reducible; O oxidizableBack to article page
