Figure 3
(a) SEM-BSE image acquired at the periosteal area of the perissodactyl bone cross section. The inset denotes part of the area where the SEM-EDX maps were recorded. (b) SEM-BSE image and corresponding SEM-EDX elemental maps (bottom) recorded at approximately 1.2 mm from the periosteum. Fe (hydroxy)oxide precipitates fill Haversian canals (Fe,O maps). A small Mn contribution was detected in a Fe-rich precipitate (Mn map) while Si and Na form small precipitates near holes (Si,Na maps). Notation: FeOx, Fe (hydroxy)oxides; Si,Na, (Si,Na) mineral; CaP, apatite; CaCO3, calcite.  [article HTML]
