Metallographic examination and analysis of six iron meteorites, two Group IVB ataxites, three plessitic octahedrites and one anomalous ataxite, have permitted their thermal histories to be reconstructed in detail. The fine matrix structure of the IVB ataxites is shown to consist of Type III plessite, formed by the decomposition at low temperatures of Type II plessite during cooling. The matrix of the other four meteorites comprises Type I plessite, which has undergone further decomposition. All of the meteorites studied showed clear microstructural evidence of exposure to a shock pressure of less than 120 kbar, followed by recovery to varying degrees. One of the IVB ataxites and one of the plessitic octahedrites have been reheated and structurally modified after the shock, and possible origins for this event are discussed.
