(a) Combined MCR-ALS scores. SEM observations of the corresponding Areas are given for comparison. (b) Schematic representations of some overlaps of the spatial distribution of the six components (Comp.) of interest among the 8 pure components identified by MCR-ALS. It highlights that organic compounds are mainly spatially associated with saponite and Fe-rich yellow serpentine minerals. Ol, w-Srp, vw-Srp, y-Srp, Sap, orga stand for olivine, white serpentine, white serpentine in late vein, yellow serpentine, saponite and organic compounds, respectively.
