Meteorite identification

[stuart7]

I found this a few months ago and I have had one geologist look at it and they couldn't tell me what it was, I have since had a search around online and found that it has alot of features that a meteorite would have, it is magnetic and pretty heavy for its size.
If anyone can help with this it would be much appreciated

"Bread-crust" type volcanic bomb

That's more than 300 million years old?

OK so curve ball🤣 I took this to 2nd geologist who specialises in minerals and she told me that this is just a pyrite nodule, she said it with confidence and with no excitement so I'm going to presume it's rubbish🤣, would you guys agree with this or?

A mineralogist told you it was Pyrite so you presumed their opinion is rubbish?

Am I on the Treasure legends forum?

The mineralogist may be incorrect in her assessment but her answer does fit the photos provided. Maybe a third , fourth or fifth opinion until someone comes up with an acceptable answer?

I meant I presume this is rubbish talking about the rock itself not her opinion, she seen the rock in person but she didn't spend much time looking at it as I took a few things for her to look at

Personally, I wouldn't agree... but then I haven't been able to examine it in hand. Who am I to argue with a geologist?

If it is pyrite then it will streak black or greenish-black on the unglazed side of a porcelain tile. Streak firmly once or twice rather than rubbing to and fro, then blow the dust away and examine the colour of the streak itself.

I'm definitely going to give that a try, time to lift the old cistern lid

The streak test is a method used to determine the color of a mineral in powdered form. In this test, the mineral is scratched against a ceramic plate known as a streak plate and the resulting colored streak is observed.

For magnetite, the streak is typically black. When the mineral is scratched against a streak plate, it will leave a black streak.

For hematite, the streak is reddish-brown. If hematite is scratched against a streak plate, it will leave a reddish-brown streak.

For pyrite, the streak is dark greenish-black or brownish-black. When pyrite is scratched against a streak plate, it will leave a dark greenish-black or brownish-black streak.

It should be noted that the streak color can sometimes differ from the actual mineral color, so the streak test is a useful tool in mineral identification.

At lower temperatures (<about 800 K) and higher oxygen concentrations, pyrite will be directly oxidized. The direct oxidation process follows the unreacted core model and may be controlled by chemical reaction or the inward diffusion of oxygen due to the pore-blocking effect by the formation of ferric/ferrous sulfate.

Iron oxides (mainly hematite, Fe2O3 and magnetite, Fe3O4) are the main products of the oxidation of pyrite. Hematite usually forms at lower temperatures (<1173–1273 K) and at high oxygen concentrations, whereas magnetite usually forms at higher temperatures and/or at low oxygen concentrations.

It is not possible to make pyrite (also known as fool's gold) at home. Pyrite is a natural mineral that is formed in geological processes over long periods of time. It is not something that can be artificially created in a home setting.

Don't cut it, there is nothing spectacular inside, it is more valuable uncut

If it is a meteorite it doesn't hurt the value.

The hopes of it being a meteorite are gone I'm afraid 🤣

Just ask chatgpt and it sounds almost exactly like what clay posted

Tell me this isn’t true. I have much disrespect for those that use AI to appear intelligent.
