Abstract

A more or less circular high-amplitude telluric conductivity anomaly is located at Magyarmecske, in southwestern Hungary. The authors collected and reinvestigated all available geophysical data previously measured in the area; based on this information it was concluded that the conductivity anomaly may well be explained as a buried impact crater. It is assumed that when the impact occurred, the target area was covered by a thick, coal-bearing Carboniferous sedimentary sequence. The projectile created a complex impact crater in these deposits, of a diameter of approximately 6–8 km. In the neighborhood of the crater the coal was modified by the impact's heat and pressure. Later the impact structure was partly eroded, partly deformed by younger tectonic movements, and covered by Neogene sediments of strongly variable thickness.
