(A) k3-weighted EXAFS spectra of ferrihydrite (Fh) and goethite (Gt), over k range of 2 – 13 Å−1. (B) Corresponding radial structure functions, over R range of 0.5 – 4.0 Å. Details about these minerals are in Table SA4, and their continuous Cauchy wavelet transformed EXAFS spectra are in Figure SA3.
