Orientation relationship of Widmannstätten plates in an iron meteorite measured with high‐energy synchrotron radiation

The orientation distribution of the Widmannstätten plates was measured in a sample of the Gibeon iron–nickel meteorite. The measurements were made with high‐energy synchrotron radiation at beamline BW5 at HASYLAB/DESY in Hamburg using a high‐resolution `moving‐detector' technique. The measurements reveal a continuous range of orientations stretching out from both sides of the Nishiyama–Wassermann orientation to the Kurdjumov–Sachs orientations, as well as a minor `spread‐pipe' between the Kurdjumov–Sachs ends of neighbouring non‐coplanar orientation variants.
