TEM images (a, f, g, and h). Selected area electron diffraction (b) and HRTEM image (c) of a single, hexagonal prism crystal of magnetite. The diffraction pattern corresponds to the zone axis of the magnetite crystal. EDXS obtained from a crystal with visible iron oxides (d). EDXS obtained from a particle-free region (e). EDXS analysis of one globule (i) showing the important presence of O, Mg, P, and Ca; labeled area in (f). EDXS analysis of two globules (j, k) showing the important presence of O, Mg, P, Ca, and S; labeled areas in (g). EDXS analysis of one globule (l) showing the important presence of S; labeled area in (h).
