Valence Determinations and Oxybarometry on FIB‐Sectioned Olivine and Pyroxene Using Correlated Ti, V, and Cr Micro‐XAFS Spectroscopy: Evaluation of Ion‐Milling Effects and Application to Antarctic Micrometeorite Grains

Valence Determinations and Oxybarometry on FIB‐Sectioned Olivine and Pyroxene Using Correlated Ti, V, and Cr Micro‐XAFS Spectroscopy: Evaluation of Ion‐Milling Effects and Application to Antarctic Micrometeorite Grains

X‐ray absorption fine structure (XAFS) spectroscopy methods have been applied to focused ion beam (FIB) produced sections of olivine and pyroxene for determining the valence states of Ti, V, and Cr and inferring oxygen fugacities of formation for each element....
