High-resolution electron-energy loss near-edge fine structure (ELNES) recorded in a scanning transmission electron microscope (STEM) is shown to provide information on the local structure and bonding of specific types of atoms in minerals. The L2.3 ELNES from Fe (Fe2+ and Fe3+), Mn (Mn2+, Mn3+, and Mn4+), and Cr (Cr3+ and Cr6+) show valence-specific multiplet structures that can be used as valence fingerprints. In general, the L3 edge for a specific 3d transition metal exhibits a chemical shift toward higher energy losses with an increase in oxidation state. Examples of mixed valence Fe- and Mn-bearing minerals are presented where the presence of multiple valence states is distinguished by a splitting of the L3 edge. -from Authors
