We have measured the habit planes of plate rhabdites [(Fe, Ni) 3 P] with respect to the parent kamacite phase (α, Fe‐Ni) in eight hexahedrites. This was accomplished using x‐ray diffraction plus two‐surface trace analysis. Results show that plate rhabdites form on either {001} or {122} planes in the parent kamacite. The meteorite Uwet exhibits a {112} habit plane which is possibly an anomaly due to the occurrence of a large shock event during rhabdite nucleation (∼ 550–650 °C).
