Explanation: Diffraction patterns from X-ray diffraction computed tomography (XRD-CT) of Martian meteorite NWA7034 or Black Beauty and Rietveld refinement of these. The diffraction patterns are from areas with high neutron attenuation and areas of low neutron and high X-ray attenuation corresponding to, respectively, H-rich and H-poor areas. This dataset contains three folders: "diffraction patterns" which contains the diffraction patterns for the three analysed clasts and the matrix. Diffraction from the H-rich areas in files labelled "_highN" and the H-poor areas in files labelled "_highX"."linear backgrounds" which contains the manually defined flat backgrounds for all of the diffraction patterns. Same naming convention as the diffraction pattern files. "maud analysis" contains the Rietveld analysis performed in the "Maud" program in files named "Refinement " and the data used to plot the two supplementary figures in files labelled "maud_clast1" and "maud_clast3". Methods, materials and software: Segmentation of X-ray diffraction patterns from the XRD-CT was performed in Python file "XRD-CT_analysis.ipynb" (https://github.com/msaca-okse/Multimodal_CT_Black_Beauty). Rietveld refinement performed in Maud (Lutterotti, L. (2000). Maud: a Rietveld analysis program designed for the internet and experiment integration.
