Roter Kamm crater

The meteorite hit a layer of Precambrian granitic gneiss that is part of the Namaqua Metamorphic Complex, overlaid with some younger sedimentary rocks. No parts of the meteorite have been found, suggesting that it completely evaporated upon impact.[2] The meteor that hit it was approximately the size of an SUV.[3]

The Roter Kamm impact structure exposes a large volume of cataclastic/mylonitic and pseudotachylitic breccias in the basement granite and gneisses, which is unusual for small craters.[4] Anomalous quartz found at the rim of the crater, and the primary fluid inclusions in the quartz, seem to provide evidence for post-impact hydrothermal activity, generated by impact heat, at the Roter Kamm impact crater.[5] Eolian and alluvial processes each played a role in modifying the Roter Kamm impact crater since its formation. Much of the more recent history of crater modification relates to eolian processes. Active mobile sands largely bury the crater and effectively mask most of the signatures associated with prior activity by other processes. Ongoing eolian erosion is responsible for scouring of the exposed rim.[6]
