Research interest: Interaction between fluids and rocks in the shallow crust

My project is about fluid-rock interactions in the upper crust. The aim is to determine origin, velocity and timing of the fluid flows (episodic or continuous expulsion) in a fracture network of a foreland basin (Great Cumbrae Island in Scotland and the Northern Variscan front in Belgium). For that I’m studying the geometry of veins and their associated halos, and combine it to their mineralogy (SEM), chemistry (portable XRF) and isotopic (SIMS, LA-ICP-MS/MS) data and the associated host rock. The mineralogy combine to the isotopic and chemical data will reveal the origins of the fluids, and the modelling of the fluid flow combine to the geometry of the veins and halos will allow me to determine the timing of the fluids. This complete study should also allow to enlighten element mobility in those fluid flow systems.
