a Zn K-edge XANES spectra of selected Zn reference compounds (solid lines) and respective target transforms (dotted lines, Table 3) calculated with the first 7 components from the principal component analysis of 20 rock XANES spectra (Table 2). b Bulk and μ-XANES spectra collected on selected limestone samples (solid lines) and corresponding LCF spectra (dotted lines). LCF results are provided in Table 4. Vertical lines at 9,663.6 and 9,667.3 eV mark the upper point of the ZnS and Zn-goethite white lines, respectively
