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

<div>(a) Sketch of the spatial distribution of veins within the outcrop. In the footwall, three systematically oriented vein systems (F1 to F3) (b) evolve to randomly oriented veins located next to the fault core (c). In the hanging wall, only randomly oriented veins are observed (d).</div>
