a BSE image of C0033-01 after epoxy fixation. The magnetite vein is highlighted in yellow. b High-resolution SR-XRF overview scan (200 nm step size) of the magnetite region presented in a. Unlike the BSE image that includes only surface information, the SR-XRF image includes additional SR-XRF signals received from subsurface layers of C0033-01, which extends to a broader area beneath the surface. The SR-XRF overview scan is displayed as an RGB image showing the K-line intensities of Ca (Red), Fe (Green), and S (Blue). Confocal point analyses #1, #2 and #3 are indicated with a cross
