any idea on what I could be? Any info is appreciated also found what looks like an impact crater near by on reef will attach pictures later mahalo

What kind of a magnet did you use? Where did you use it?

 

[Tuberale]

Can you show the impact crater too?

Not a meteorite. Please pick up a few guidebooks on meteorites. I find mine very helpful.

Time for more coffee.

I used a cheap speaker magnet the grey you see is the inside of the stone I filed a corner to get under the red ant that was the result as for the magnet it had attraction around the whole thing I broke a piece of the red crust that also stuck to the magnet I’ll have a post of the crater tomorrow I also found this near by with the same magnetic results that stones weight is 32lbs

I also had a pretty knowledgeable friend take look at it and he said he thinks is a really old meteorite

The pits in the surface are a dead giveaway as is the angle of the break, this is not a meteorite, probably a lava bomb

The rock shown in post #6 appears to be basalt, and has no visible characteristics of meteorites.

Time for more coffee.

Thinking about it for a few minutes, and I believe Alan could also be correct. While most lava bombs I have found are a red lava, my neighbor has a few that are gray and one that is black. So it is, based on images, a basaltic lava bomb.

Still not a meteorite.

Still time for more coffee.

Thank you I saw a clip on YouTube where they said that stones from mars have a grayish basalt under the red similar to terrestrial basalts is that true?

And the breaks were done by me the large stone In 6 i took a sledgehammer and a forming pin to it the smaller stone I dropped a few times then pulled it apart both were found at the same beach in the water I’ll post the pic of what looks to be a small impact crater tomorrow sometime

Crater pic would be awesome and might be some meteorites there if it is a crater cant wait to see it
