What is this rock? My detector is picking it up.

Can anyone tell me what this rock is? I'm thinking it's granite, maybe? I've posted a video of it....

Don't know... maybe a meteorite ?
Maybe a really mineralized rock ?
Maybe gold in them there rocks....

I'm cracking up so hard!!!

I Don't think Granite has metal in it.
at least not naturally.
I also don't think Gold, since you maxed disc .
other then that I can't help exept too ask
are you absolutely sure it's not Cement
with a coin, Piece of Wire or Brass in it ?

 

[Swartzie]

My guess would be some kind of slag.

@Jeff according to the internet, granite has metallic properties.

@Swartz isn't slag black?

I don't know...thanks for the responses.

Well, first off it DOES look like a granite type of rock and not concrete.
Slag could be any color based on what metal the slag is coming from, but that's not slag.
Since it's just a rock, take a hammer to it! Find out WHAT is causing the response.

 

[ivan salis]

metallic minerals within the rocks "make up" cause a "hot rock' effect -- (ie) it rings up due to mineral content within the rock

It looks like some of the HOT ROCKS I have run across while prospecting out west. They usually contain iron. I am surprised no one asked. Did you test it with a strong magnet? Frank

No didn't use a magnet on it, but I will Frank. Great suggestion Sir! Thanks!

Put the rock in the microwave & cook it for about 30 minutes.....see if you're microwave starts sparking...& still works after the 30 minutes. Then afterwards.....instead of "hot potato".....you can play "hot rock"......bet the rock stays hot longer than a potato anyway...

Nice try, and an intelligent thought. But please look again. My right hand doesn't have a ring. My wedding ring is on my left. The rock is where it's coming from.

Here's an odd one. While prospecting out in the slabs near the Chocolate Mts. I got a responce from a small rock. I picked it up and wiped it off for inspection. It just looked like a rock. I checked it and the ground with the detector and got no responce. The next time it happened, I picked up the rock and just checked it. I got a responce! I then wiped off the rock. The responce vanished. I was working a dry wash and some of the rocks were covered with flour gold. From then on I wiped them off in a zip lock bag. Live and learn and earn. Frank

Can you manually ground balance this machine ?
I have seen a Tesoro pick up hot looking rocks on the beach that my DFX would not sound off on
in all metal mode...
Long ago I remember rocks like this, that would pick up all the way on max descrim and you could
ground balance this out with a manual ground balance machine....

maybe...

Flour gold will not cause a detector to respond.

Gosh, I wish I had manual ground balance. My Garrett is automatic.
