New aspects of synchrotron Mossbauer microscopy are presented. A 5 mu m spatial resolution is achieved, and sub-micrometer resolution is envisioned. Two distinct and unique methods, synchrotron Mossbauer 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 Fe-57 phantoms, and on samples with natural isotopic abundance, such as meteorites.
