[meteorite-list] Iron in a stone?

[Aleksandr V. Leonenko]

Greetings to all!
 I want to ask, whether really these oxidized sites can be the oxidized 
iron? If isn't present, what it is a mineral? Whether there can be this 
stone a meteorite?
  Stone not маgnet. It is found on a calcareous plateau. It would be 
desirable to know your opinion.
