Hello Jeff and List,
Here is some information from Buchwald that may prove helpful
in identifying schreibersite and cohenite in hand samples:
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)
Schreibersite (p. 104):
- schreibersite is magnetic
- it is y e l l o w in reflected light
- compared to cohenite distinctly more brownish
- softer and much more brittle than cohenite
See also: O.R. Norton (2002) Cambridge Encyclopedia of
Meteorites, Appendix C, Minerals in meteorites (pp. 311-313).
Best wishes,
Bernd
