Figure 3
X-ray fluorescence maps of a 300 µm × 300 µm region of interest in a dissected soil aggregate sampled from the BC horizon of a forest soil near Balingen, Germany. (a) Map of total Si acquired with an X-ray energy of 2483 eV. (b) Map of total S acquired with an X-ray energy of 2483 eV. (c) Map of reduced S acquired with an X-ray energy of 2474 eV. (d) Map of total Si acquired at with an X-ray energy of 7200 eV. (e) Map of total Fe acquired with an X-ray energy of 7200 eV. (f) Map of elemental and divalent Fe acquired with an X-ray energy of 7121 eV. In maps (b)–(f), increasing concentrations of the elements or element species of interest are represented by a colour change in the sequence blue–green–yellow–red. |
