I am stumped with this rock. I have never had one cause such an overload on my metal detector. I have a new Minelab Safari and took it to the beach on Block Island RI. It signaled gold and of course we dug, dug, dug. About two feet down, there were rocks, and we took them out of the hole one by one. This rock was the cause of the beeping- and every time we test it, it causes the machine to "overload" with such a strong signal. The dark grey residue definitely rubs off easily, you just have to handle it to see grey on your hands and if you use the rock like a pencil, it writes like one (like it is graphite or something-see photo link below)

It is weathered like a river rock in the water. I don't know if that vein is what is causing such a ruckus with the metal detector or the rock itself. There is a vein of quartz and shiny material that runs through the rock. Any thoughts?

sorry, not sure what a "hot rock" is, can you explain? It is not magnetic if that helps narrow it down.

I googled all the rocks that could be "Hot Rocks" from that site and none of them look like this one. It is not magnetic, writes easily on paper and is not flakey... strange.

There has been a discussion under "today's finds" topic if you have time, let me know what you think after reading the discussion there-
http://forum.treasurenet.com/index.php/topic,416400.0.html

I appreciate your help!

Thanks, fun to learn!

Lol yeah, those folks get a bit more deep and technical than i do. To me, if i dig it and it ain't stamped with a hallmark...it ain't gold! ;D
Best to listen to them before me, i was just offering an opinion on what i'd class it as...just before i threw it back in the hole.

By the way, If nobody told you over there then i'll tell you here in stages so you can load pic's better.

1/ Google "photobucket"

2/ Join (free)

3/ upload your pic's there

4/ Hold your mouse cursor over each pic' and a drop down list will show

5/ Put the cursor over the "IMG code" and copy it (left click it and it autocopies)

6/ Write your post here and then paste the IMG code where in your post you want it to show

7/ Post your thread. Done!

Photobucket automatically resizes your pic's to fit here. Hope this helps. :wink: :thumbsup:

I found a very similar rock like that among some slag from a foundary. I was told it was magnesium by an exfoundary worker. It looked and acted the same as yours. Don't get it around a fire! If it is magnesium it will burn very hot and water won't put it out, rather it could explode. It burns very similar to military white phosphorus. I shaved of just enough of the rock I found just to make a very fine powder (a tiny amount) and lit it up with a fire starter stick. It burned with an intensity and burned out within just a few seconds. The smoke had a garlic like odor. I am not recommending you try this unless you put it outside on a fire safe surface such as concrete and wear eye protection. Monty

Monty PLEASE DON'T encourage people to try this even on concrete the heat generated can or will cause the concrete to pop or explode!! HH
