Abstract
We present a set of new data on microtextures, mineral composition, bulk composition and microhardness (Hv) of kamacite, phosphide and sulphide in Raghunathpura IIAB iron (structurally hexahedrite). Based on textural studies, we find Raghunathpura comprises of a single kamacite grain studded with exsolved inclusions of tiny schreibersites and trapped melt inclusions of troilite often superposed with numerous sets of Neumann lines. Compositional data further suggest that Raghunathpura is an early crystallised IIAB iron with low Ni, low P, low S and high Ir. Metallographic cooling rate of 7°C/Ma has been estimated from phosphide composition-size relationship of this rare group of iron.
