Fluid Dynamics in a Thrust Fault Inferred from Petrology and Geochemistry of Calcite Veins: An Example from the Southern Pyrenees

Figure 9

(a) Crossplot showing the δ¹⁸O and δ¹³C compositions of the calcite cements, host rocks, and fault rocks (carbonate matrix from the cataclasite). Cretaceous marine limestone values (green box) are from [53]. (b) δ¹⁸O values of the calcite cements versus δ¹⁸O values of the related host rocks.
