BSE image and Nano-SIMS measurements of a clinopyroxene crystal affected by the fluid influx and surrounded by newly formed sodic amphibole. The brighter areas in the BSE image are marked by a sharp reaction front (dash-dotted line) behind which the cpx crystal has a pathy zoning. The reaction front and the patchy areas (stippled outlines) are clearly reflected in the isotope images. The bright areas in the BSE image correspond with elevated hydrogen contents (indicated by the 1H28Si/28Si and 1H16O/16O mappings) in the nominally anhydrous cpx. Clinopyroxene is defined as Cpx and sodic amphibole as Na-amph
