The tomographic images revealed characteristic Windmanstttan patterns, intergrowth of kamacite and taenite, which provide information about how quickly the meteorite crystallised between solid and liquid and how the concentrations of nickel and iron changed as the meteorite cooled down (a few degrees every million years).

Volume rendering of one of the samples, the Muonionalusta, allowed the investigators to characterise the kamacite lamellae and confirm the meteorite had a fine octahedrite structure.

Studying the mineral composition and structure of the Morasko meteorite, Buchwald (1975) noticed that kamacite had locally undergone an extensive change to a granular pattern, and the cohenite crystals had markedly recrystallized.

Several micrometeorite grains have unaltered kamacite cores, which is an additional evidence for their common origin with the meteorite fragments.

Occurrence: Associated minerals are: kamacite, taenite, troilite and forsterite.

Nickelphosphide

Occurrence: The grains in Indarch probably formed by exsolution of Si and N from kamacite, perryite and schreibersite during parent-body metamorphism.
