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

<div>(a, b) Plane-polarized light and cathodoluminescence microphotographs of the footwall host rocks consisting of a grainstone made up of corals (c), foraminifers (f), bivalves (b), echinoids (e), and peloids (p), cemented by calcite (Cc0). (c, d) Plane-polarized light and cathodoluminescence microphotographs of the hanging wall host rocks composed of a wackestone of calcispheres and planktonic foraminifera.</div>
