Ok I need to know if this is something anyone else has come across and can tell me what it is. I found four very heavy hematite like rocks i guess but I can see different mineralization on two of them. One I think magnatite and the rest I'm not sure. Two look burned and more colorful. But what has me perplexed is the silvery thick metallic matrix that's inside and cubed at top and i guess dense at the bottom then branching out to the several cubic and irregular shaped top pieces. All have similar interior but different in some ways bc of size differences and maybe ground shifting. Vaguely magnetic which was surprising with so much metal. My first thought was slag but it's usually completely melted right? This is not inside just some of the outside. Any ideas????

Nice find. Sorry I can’t help with the ID. Welcome to tnet from Niagara Falls.

Limonite (psedomorph) after pyrite would be my guess.

It may be. Two of the rocks are clearly limonized. I had a thought it could be a hematite quartz specular inside bc its silvery color reminds me of those hematite rose specimens. But are those magnetic? bc this is not highly magnetic like I would think this type of iron ore hematite would be. Idk I am still trying to learn more about what I collect but it is much to take in. Lol

Hematite is non-magnetic. Magnetite is magnetic.
Best way to test: Rubb on unglazed porcelain. Brown (streak) color indicates limonite. Reddish indicated Hematite.

The only thing about that is the red mud is like it's baked or silicified throughout it so I'm afraid that wouldn't be reliable. Is there anyway that stuff inside could be silica in that particular formation.
