Humic substances (HS) were extracted from faecal “pellets” - ovoid phosphatic grains 50-200 µm in size - collected from commercially mined phosphatic sediments, in the Gafsa Basin. The phosphatic constituents were characterized by C, H, O, N, and S elemental analysis, Rock-Eval VI pyrolysis, Fourier-transformed infrared spectroscopy (FTIR) and solid state 13C CPMAS NMR.
