Neutron activation analysis of 15 samples from widely separated locations on the surface of the 28-t Armanty (Xinjiang) group-IIIE iron meteorite showed no compositional variations attributable to magmatic fractionation processes such as fractional crystallization. The homogeneity contrasts with that observed in the Cape York IIIAB iron, in keeping with the idea that the latter is an exceptional case. From the maximum compositional gradients the radius of the IIIE core is estimated at greater than 1 km. One sample taken from a surface formed by fracture associated with its fall to Earth is slightly anomalous in composition. It is suggested that this region is near the border between two parental gamma crystals and has a high content of minor phases.
