Fig. 3

Light microscope image of a thin-section from limestone S151 and corresponding μ-XRF maps for Zn, Fe and Ca. The mapped area is 3,000 × 3,000 μm2 (20 × 20 μm2 resolution, 100 ms dwell time). The horizontally and vertically smeared-out signal around POI2 observed on the Zn distribution map is due to the intense Zn signal at this location, partially causing saturation of the detector
