Photographs of processed and shocked samples. (a) Photograph of the cut samples, showing a semicircular Fa₅₀ olivine slab with a thickness of 1 mm and a diameter of 12 mm. (b) Photograph of the sample mounted on a copper holder, prepared for shock experiments. (c) Photograph of the shocked sample embedded in the recovery target. The flyer plate exhibits inward deformation due to the shock impact at 18, 31, 41, and 47 GPa. (d) Photographs of the shocked samples after recovery using a lathe, with the samples remain enclosed within the residual copper sample holders. After impact, samples subjected to 18 GPa and 31 GPa exhibited substantial fragmentation, with the resulting powdered samples appearing greenish white. Meanwhile, the 31 GPa sample was partially melted and appeared black. At higher shock pressures (41 GPa and 47 GPa), melting occurred in the impacted olivine, resulting in a predominantly black appearance.
