New aspects of synchrotron Mössbauer microscopy are presented. A 5 µm spatial resolution is achieved, and sub‐micrometer resolution is envisioned. Two distinct and unique methods, synchrotron Mössbauer imaging and nuclear resonant incoherent X‐ray imaging, are used to resolve spatial distribution of species that are chemically and magnetically distinct from one another. Proof‐of‐principle experiments were performed on enriched 57 Fe phantoms, and on samples with natural isotopic abundance, such as meteorites.
