Meso- and micro-scale textures resulting from fluid infiltration into the sampled rock. a A sharp reaction front in the meter-sized block marks the extent of fluid infiltration (bluish areas) into the dry eclogite (greenish areas). b Back scattered electron (BSE) image of a fluid-induced reaction zone. Initial fluid influx in porous areas modifies the clinopyroxene (Cpx) composition (patchy areas). Subsequent formation of sodic amphibole (Na-amph) from sodic-calcic amphibole (NaCa-amph) and cpx is associated with up to 1 µm wide reaction zones (solid arrows). c BSE image of the fluid-induced reaction zones in cpx showing the patchy zoning (white cloudy areas) and the associated interconnected pore space together with the formation of sodic amphibole. The red lines mark the positions of the FIB sections from Figs. 2 and 3 taken across the reaction zones
