Hey Outback , yes used that for my Black Springs find & passes every test , so it will eliminate a high percentage based on those facts alone. The decider is the nickel iron presence

Might have to take the 5000 out there with me next time there for a poke around and see if there's any more, a meteorite would be cool .

Interesting site mate, I have found a weird rock that is not magnetic  and does not reacts to detector but very heavy. Any idea?

Sorry for opening an old post here, but from what I know some meteorites contains a lot of Silicon Carbide ( SiC ). A 9 volt battery and a couple of wires to the rock should make a slight glow between the negative wire and rock, just as a LED would glow. I could also be mega wrong here, but possibly worth a try. Silicon Carbide can 'simply' be made by smelting clay (aluminum silicate) with coke (carbon) at 1600'C in a graphite crucible ( Lely process )

Me too.

To me it looks like it has a texture inside that might be diagnostic, but you might not want to cut it to see. Ni_Fe meteorites (with SiC) are magnetic. Even stony meteorites would probably give a small response to a hand magnet. SPecific gravity is always the best way to start - unfortunately after that you usually need to either analyse a piece or cut it.

Have you resolved it by now?

That's correct , notice most meteorites are found over in NSW were you can keep them lol

This is one I found & cut to show the metal inside .

One of these is not a meteorite ' can you tell by just looking ?

Cool stones though

OK I'll show what one big_smile very hard to tell from just a photo guys but thanks for giving it a try .
The cube is one CM square .

It's the ironstone bit on the left that's been desert varnished , the middle meteorite is a stoney & on the right a rare type called a mesosiderite
Here they are cut open :

That's an awesome test Outback! Very hard to tell by the inexperienced. I would have chosen as the others did for sure! Why would we hand over anything to the government? I think they tax us enough and keep enough from us all. If in WA and lucky enough to find a meteorite, I say what meteorite??
Thanks again Outback thumbsup

Very interesting Outback, I will certainly be looking at lumps of ironstone with a different perspective from now on. smile How is the best way to identify a meteorite in the field? Or should suspect rocks always be brought home for further investigation?

That's easy Heatho, Space nuggets (meteorites) will be the ones with alien footprints either side of it. lol

Thanks 'pleased you enjoyed it smile
Most states have laws banning the collecting of meteorites , this has wrecked the science regarding where they were found as most will have a re-birth somewhere else .
A meteorite is just a rock until it's been classified as one wink

Hi Heatho ,
First off I use a golf club that's had the blade cut off & a strong rare earth magnet glued on the end , almost all meteorites are magnetic so using the club allows me to touch rocks without having to bend down .
I hunt in places that has few dark coloured rocks & check out any possible looking ones , I'll then take some back to the vehicle & use a diamond file to have a quick look under the surface .

Pic of spot we went looking for them :

Cool pick Outback cool looks like the middle of nowhere yikes
Are the meteorites more magnetic than the ironstone? or are you taking anything magnetic for later testing?

Yes meteorites are mostly more easy to identify from there magnetic strength , but that can be from weak to strong , they are also show degrees of weathering depending where they fell on earth .
In a dry desert it slows down , some on the coast only last a couple of hundred years depending on size & type . Iron ones last the longest .

Meteorites from the moon & Mars are not magnetic , they are so much more valuable then gold per gram .
