Petrologic textures of the studied winonaites. a–c Representative areas of NWA 725 with relict chondrules (e.g., Figure 2c). d, e The representative areas of NWA 6448 with fine-grained texture. f, g Representative area of GRV 022890 with medium-grained equigranular texture. h Two euhedral clinopyroxene crystals are enclosed by plagioclase in GRV 022890. i, j Representative areas of GRV 021663 with coarse-grained olivine-rich texture and metal veinlets. k Representative area of NWA 4024 with the coarse-grained metal-rich texture. l Curvilinear trails of metallic FeNi blebs (white) in mafic silicate grains of NWA 4024. The labeled minerals include olivine (Ol), orthopyroxene (Opx), clinopyroxene (Cpx), plagioclase (Pl), FeNi metal (Fe–Ni), troilite (Tro), and Fe-oxides (Oxi).
