There are a few simple tests that will better your odds of a positive ID. If it is magnetic with strong attraction, most likely it is an iron core meteorite. If weakly magnetic, it might be a nickel core meteorite. If not magnetic at all, it might be a simple rock meteorite. All three types are found all over the world scattered nearly equally. Confused? So are most of us. The proof is in cutting one. Sadly, the absolute truth in analysis also means your sample is no longer pristine. Nature of the beast though.

Have a Google search on identifying meteorites and see what turns up. It'll keep you reading for a long time.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

soil disturbance age looks to be over a thousand years, comparing the pictures I have seen with the area in question.



Clay is pretty common in the area, high moisture content in the soil will reduce the effectiveness of the GPR as well correct?

I will see about getting a core sample, the area is not...easily accessible until summertime anyways so got a bit of time to research.


On GPR rentals I see SIR 3000s rentable for around 120-150 per day from environmental supply and pulseEKKOs for 160 per day from apollo geophysics, that seem reasonable?

Thank you for the input so far, appreciate it.

Re: GPR rental prices. I'm assuming the currency you are using us the USD. If so, it's reasonable. I had been quoted close to USD450/day for a Mala GPR. Prodigious amounts wet clay will severely reduce penetration depth. Good luck! Smiley

You could also bet that this was a metallic meteorite and make a general survey of the whole area using a magnetometer. It will easily detect any sizable object/remain made of iron/nickel/... alloy much deeper that any metal detector on earth.
If nothing is found, too bad, it was probably a rocky meteorite.

If you're interested, I can help you.

I don't believe GPR will work at any depth like 30 feet or meters.
If you look at the LandSat Radar stuff only in the driest deserts will it penatrate at all.
The delectric constant of water is 30 that of dry materials is something on the order of 2-5.
This means that there is a nice reflection on anything moist or wet.
