Hi Mojito, i have handled thousands of meteorites. Unfortunately your rock is not one.
But dont stop looking almost every detectorist will detect one or two in their lifetime and most will be old weathered looking rocks that they will discard as hot rocks. Even without a detector it is possible to find them but you need to know what weathered ones look like, not the fresh as or cut ones you see in museums and ebay.

Hi RedDirt,
Thanks very much for your advice, I appreciate it. Just out of curiosity and for educational purposes, why don't you think it's a meteorite?
And I'll definitely keep looking. I'd love to find one.
Cheers,
Moj

Hi Moj, i was probably a bit ruthless. Get it tested there are some meteorites with unusual mineralogy and it could be one
But the desert glaze on the surface and the iron weathering skin on it with fresher lighter material inside just doesnt look right
Cheers rdd

Red Dirt Digger..What do you think of the rock I posted..It is Non magnetic..But is heavier than I think it should be..Cheers..

Unfortunately, with meteorites I think you'll find that those two qualities don't go together. For a meteorite to be "unusually heavy", it would have to be a nickel-iron type (like Australia's famous Mundrabilla fall https://en.wikipedia.org/wiki/Mundrabilla_(meteorite) ), but nickel-iron meteorites ARE magnetic.
Where it is, there it is.

Goldierocks??,
I saved this rock. It ticks all the boxes, it's magnetic, appears to have molten edges and a pitted surface. Found with a metal detector, nice signal.
Any comments are welcome. (It's been haunting me for ages).

Grubstake ..Aparently not all meteorites are magnetic..Evie/Bee ..yours has sharp edges it should be roundish I recon..

I know that and as I said above, the non-magnetic ones aren't especially heavy either.

That photo looks similar to Henbury meteorites , file a bit off it & post a photo , you could be in luck .

Outback; It's a fragment of a much larger piece, I found it in the Murchison.
Here's 3 photo's of the back side. The longest side is about 3 inches.

I'm getting a good feeling about this rock , that 3rd photo seems to show a roll-over melt ridge that could have been caused when it came through the Earths atmosphere at huge speed creating super high temperatures .
Would need to see the interior to be more accurate .

I'm more experienced with gold than meteorites, do you think i should give them a look at it at the Perth museum or somewhere else?

I have a suspicion that this stone has been knapped. One side looks very much like a knapped scraping stone, but that is not saying it is not a meteorite, just that someone else may have found it before you, converted it and used it as an implement.

Sure ' have some knowledgeable meteorite collectors have a look at it , for it to be a officially recognized as a meteorite ~ classification is required .
Now this is where I have to be a bit guarded in what I say because of the law of ownership and control of meteorites in Australia .
As far as I know only in NSW meteorites can be found , kept & sold on but not exported without a permit .

Hi Mojito,
Im an avid meteorite hunter, from the United States... , your rock does not look like a meteorite, but pictures are not the best resource. Put a window in it, or slice it open with a rock saw, and look for nickel iron flakes in it. There is a lot of info on putting a window in a meteorite..

I am thinking that you may have some foundry slag there.

First Geo thought it may be a form of Granitite but things from out of this World is not his forte.Gave it 50% chance from outer space.
Second Geo used words like Basalt Bundi , Flow Blended,Granitite Surpace, Crackel Breccia, Plagio Clase,Calcium Felspar.
It does seem to have heat shrinkage lines.Burn`t Crust.Heated incoming skid pad.Some magnetic attraction and a Nth / South Pole Polarity.
Tried to grind a window but the thing is harder than anything i`ve tried to resurface..
PS; please excuse the spelling of the Geo terms i have no idea of that terminology.
Whether they were blown out of a volcano.
Squeezed out of a fault crack or washed down an ancient river bed.
No idea.

Maybe get yourself a Nickel test kit and test it for nickel content. Can find them on Ebay
