Moon: ‘ghost’ craters formed during mare filling

  • 57 Accesses

  • 13 Citations


This paper discusses formation of ‘pathological’ cases of crater morphology due to interaction of craters with molten lavas. Terrestrial observations of such a process are discussed. In lunar maria, a number of small impact craters (D < 10 km) may have been covered by thin layers of fluid lavas, or formed in molten lava. Some specific lunar examples are discussed, including unusual shallow rings resembling experimental craters deformed by isostatic filling.
