Hello Listees and Listoids, Cohenite = [(Fe,Ni,Co)3C] Buchwald writes about Morasko: Cohenite is common in some sections, absent in others ... Over an area of 4 x 3 cm^2, a total of 45 cohenite crystals, each typically 3 x 0.6 mm in size, was observed. They formed rounded bodies with reentrant angles and with 50-300 ยต inclusions of kamacite, taenite and schreibersite. Buchwald about cohenite: Buchwald V.F. (1975) Handbook of Iron Meteorites, Vol. 1, Cohenite (p. 100): - cohenite is brilliant w h i t e - it is very hard, significantly harder than schreibersite - characteristic of group I irons (also occurs in other irons) Reference: BUCHWALD V.F. (1975) Handbook of Iron Meteorites, Vol. 3, pp. 836-838.
