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

<div>Paired optical and CL microphotographs from calcite cements precipitated within the fault core and fault damage zone of the studied thrust. (a) Fracture F1 cemented by calcite cements Cc1 and Cc2. (b) Calcite cement Cc2, with its characteristic CL zonation, filling a fracture F2. (c) Cc3 filling a F3 fracture, postdating a fracture F2 filled with Cc2. (d) Cc4 in the main fault plane.</div>
