Scientific paper

A small area littered with loose decimeter-sized fragments of glass and melt fragment-bearing suevite has been discovered on the western rim of the Roter Kamm impact crater in southern Namibia. The clast population and results of major and trace-element chemical analyses are consistent with this breccia having been formed from granitoid basement lithologies only, without contribution from the metasedimentary Gariep and Cenozoic cover sequences. It is assumed that the limited amount of impact melt observed in the Roter Kamm structure could be the result of melt dissipation due to explosive shock-induced devolatilization of the significant marble component of the Gariep supracrustal cover. Preservation of very limited remnants of impact breccia on the rim of the Roter Kamm crater suggests a relatively deep level of erosion of the crater rim.
