Method for generating intra-particle crystallographic parameter maps and histograms of a chemically pure crystalline particulate substance. Spectral imaging, in general, and focus-fusion multi-layer spectral imaging, in particular, combined with pattern recognition classification analysis are performed on individual particles for forming sets of single-particle spectral fingerprint data, characterized by single-particle spectral fingerprint spectra. Spectral shifts are identified in the single-particle spectral fingerprint data, for forming intra-particle crystallographic region groups each featuring sub-sets of intra-particle spectral fingerprint pattern data, where selected data elements in each sub-set are shifted relative to corresponding data elements in remaining sub-sets in the same intra-particle crystallographic region group. Each intra-particle crystallographic region group is associated with different crystallographic parameters of crystal type and crystal class, for forming intra-particle crystallographic parameter data, which is used for generating intra-particle crystallographic parameter maps and histograms of the chemically pure crystalline particulate substance throughout an entire multi-particle sample.
