...Klaus Keil Abstract Daubreelite (FeCr 2 S 4 ) was discovered by Smith (1878) in the Coahuila iron meteorite, and has since been identified in several hexahedrites and octahedrites ( e.g. Heide et al. , 1932; Perry, 1944; El Goresy, 1965, Marshall and Keil, 1965). In stone meteorites it has been...
