Fig. 6. Comparisons of SHERLOC and PIXL observations from the Jezero fan front.

(A) HDR scan of the Thornton Gap abrasion in the lower Jezero sedimentary fan. Location of the smaller SHERLOC detail scan footprint in (B) is shown in a small white square. Location of the SHERLOC survey scan in the right column is shown as the larger white square. (B) Data from the detail scan of the Thornton Gap abrasion. (C) Data from the Berry Hollow abrasion in the Jezero sedimentary fan. The left column shows scan points on the colorized ACI-WATSON image merge. Raman and luminescence detections are symbolized with colored circles and asterisks, respectively, on the colorized ACI-WATSON image merge. Open white circles indicate that no Raman features were detected. The middle column shows the 330- to 350-nm luminescence detection locations on coregistered and warped PIXL P₂O₅ wt % map. The right column shows the SHERLOC luminescence heatmap. Note the spatial association of both 330- and 340- to 350-nm luminescence to P₂O₅ hotspots (white arrow). In Thornton Gap, SHERLOC Raman detected only carbonate. Sulfate-associated 305- and 325-nm doublet luminescence in the Berry Hollow target reported in (21) are not examined in detail.
