High-angle annular dark-field scanning transmission electron microscope (HAADF-STEM) image of foil no. 5358 showing an aggregate of zhiqinite (TiSi2), enclosing globules of badengzhuite (TiP) and surrounded by Ti10(Si,P,□)7, Ti11(Si,P)10, and the dmisteinbergite-like mineral. (b) Al2O3 – corundum hosting the Ti silicide inclusion. Source areas for EDX analyses are numbered squares; filled squares indicate locations where data for the structure were obtained: no. 426 (badengzhuite) and no. 428 (zhiqinite). (c) TEM (transmission electron microscopy) bright-field image of the area inside the large square shown in (b). (d) TEM bright-field image of globular badengzhuite in zhiqinite. HAADF and bright-field images obtained at the GFZ German Research Centre for Geosciences. Mineral
