Extended Data Fig. 2: Group 3 Fluorescence Across All Targets Analyzed by SHERLOC.
From: Diverse organic-mineral associations in Jezero crater, Mars

Colorized ACI images from survey scans of each of the 3 natural targets (top left), 4 Máaz abraded targets (right), and 3 SĂ©Ătah abraded targets (bottom left). Green spots represent the relative laser beam diameter that have a positive identification for the ~270–295 nm fluorescence. No ~270–295 nm fluorescence was observed on survey scans in Garde and Quartier.
