On the geomorphology of the meteoritic crater Zhamanshin area

Abstract

The analysis of surface morphology, geological structure and relief evolution provided evidences for the meteoritic impact origin of the Zhamanshin crater in Aktyubinsk region, Northern Kazakhstan. The crater's diameter is 5.5 to 6 km, the depth up to 200 m. Geomorphological and geological data indicate the crater was formed at the end of the Early Pleistocene.
