[meteorite-list] Impactites?

[Aleksandr Leonenko]

Hi all!
Found a structure similar to the crater (40 m diameter), also found a rusty rocks. They are light and soft, it's a rock - I do not know. Not magnetic. Perhaps that impactites. But similar to limestone. Search with the metal detector with no results. Please help in the definition.
