Hello I am not sure what type of rock this is and what the gold and copper flakes are everywhere on it. It is slightly magnetic in the center (neodymium sticks well but not black magnets)
Really heavy/dense rock. I don’t know what the fusion crust burnt area is as it’s very hard and into the top layer of rock/ crust.

Comes up 80-90 on my Garrett400i

Thanks!

Looks like what you have there is a hodgepodge of various iron minerals - pyrrhotite, pyrite, magnetitie and/or hematite. All but pyrite can be magnetic, hematite only occasionally and weakly magnetic, pyrrhotite weak but increases on heating, and of course then there's magnetite.

Huh, interesting. I know it’s probably not worth anything but would it be a good idea to break/saw it in half to get a better look at its composition? Or is it better left in its original state ? I think it’s quite interesting as I’ve never seen anything like it.

Any ideas on what the black charred area is or how to describe it? Is it just minerals forming on top and only looks burnt?

I don't see anything being gained by cutting it except it will ugly-up your saw oil reeealllly good lol...I don't see the inside being anything too interesting. Pretty cool as a specimen, and the "charred" looking areas are probably just iron sulfides or oxides

I would take a small sample and get it professionally tested. Costs about $40 and you won't ruin the specimen.

I am curious of what the inside looks like haha
I do plan on taking it to a local subsurface geology lab in town but my work schedule isn’t helping.
I don’t have the correct blade/tile saw to properly cut it yet but I want to see how many or how big those gold/copper coloured flakes go and what the magnetic area in the centre looks like.

Thanks for the responses!

No I wouldn't cut it with a saw either, I'd crack it in half :) misread that, thought he said break it or cut it..
