Meteorite or not?

[endrust]

Hi everyone!
Found this in ground (about 15 cm depth). It is magnetic, and rather heavy (145 grams). The size is 56mm*46mm*20mm. Also, my detector shows that it is non ferrous metal.
What do you think, could be a meteorite?

Thanks!

From your measurements I'm getting 145g/51.52cm3 = 2.81 g/cm3. Could you maybe get a better volume measurement using water and a graduated cylinder?

Thanks for your answer. I've made measurements with water and got 145g/33,5cm3 = 4,33 g/cm3. It means that it could be a stony-iron meteorite. Maybe there is some other way to identify is this a meteorite or not? Because I'm having some uncertainties about meteorite/ore origin of this thing. Thanks!

You have a common basalt type lava.

Please buy a copy of "Rocks From Space". It will
make things easier.

It would also make things easier if you had included the author of the book you're referring to, as there are 27 of them in my library system with that title.

That would be the book by Richard Norton. It has been mentioned in the Meteorite section of the forum many times. However, since there are 27 by that title in your local library system, I would suggest you read all that may pertain to meteorites. After all, knowledge is power.

Might I just say that "ferrous" and "magnetic" are pretty much the same thing, meaning, if it is magnetic, it has a definite amount of iron. Magnetic=ferrous. Your detector is not lying. They are incapable of lying. It is just "guessing" based on the criteria presented. You may assume that ANY magnetic rock has a certain amount of iron. TTC

As an avid meteorite collector, you need to purchase O Norton's Field Guide to Meteors and Meteorites. On pages 251 and 251 he gives two ways to test for nickel in your rock. Iron/nickel in rocks is so rare that it is the definitive test for meteorites. TTC

O Richard Norton. Rocks From Space. Has a fiery rock on the cover. A classic. TTC

Thanks everybody for advices! Will try to do the nickel test, or maybe find a local laboratory.

My 2c - I also think it's lava - it looks as if it was the top of a bubble in the lava given the concave and convex surface on each side, and the breakage looks basalt'y' to me. Crack age on the surface also looks like cooling lava from an expanding bubble

Cool find

Looks like a lava bomb to me, notice the convex side and the concave side, still, it is a great specimen.

Good find Mother Nature is very crafty
