Back-scattered electron images of major constituent phases in C0094, glossy group. a Euhedral hexagonal morphology of pyrrhotite and plaquette magnetite. Some pyrrhotites show smooth surface texture. b Pyrrhotite having modified surface. c Framboidal magnetite. d Cubic-shape magnetite. e Ca–Mg carbonate, dolomite. f Coarse-grained phyllosilicate. g Circular structure-enriched region. Larger ones are indicated by arrows. h High-resolution image of a circular structure. i Melt-droplet texture includes rounded opaque phases. j Melt-aggregate-like morphology showing tiny bubbles at the surface. k Line analysis profile of a circular structure obtained by EDS
