a Map showing the four regions selected for comparison between field and virtual outcrops (A–D, indicated with Thiessen polygons of different colors) and b their respective stereonet plots (poles to planes). All data collected from the field are reported as circles in the stereoplots, while all data collected from virtual outcrops are reported as crosses. The reader is referred to Table S2 of ESM1 and Figs. S1–S4 of ESM2 for details of the different recognized clusters
