Multimodal x-ray and electron microscopy of an Allende meteorite sample

POSTER

Abstract

Correlative multimodal microscopy that combines complementary nanoscale imaging techniques is essential for extracting comprehensive chemical, structural, and functional information of heterogeneous complex samples. Advanced electron microscopy provides atomic-scale spatial resolution with quantitative elemental composition, while x-ray microscopy can achieve high-resolution imaging of bulk materials with chemical, magnetic, electronic, and bond orientation contrast. In our recent work (Science Advances 5, eaax3009, 2019), we combine x-ray ptychography and scanning transmission x-ray spectromicroscopy with 3D energy-dispersive spectroscopy and electron tomography to perform structural and chemical mapping of an Allende meteorite sample as a model system. We use textural and quantitative elemental information to infer its mineral composition and discuss potential processes that occurred. This multimodal x-ray and electron microscopy of the same sample overcomes the limitations of individual imaging modalities and opens up a route to future multiscale microscopies of complex functional materials and biological systems.
