Magnetic rock...Solved Hematite-Magnetite combo/mixture

[turtlefoot13]

Hi again,

I am posting this here plus in the rocks and gems area.

I found something that has me stumped. I found a rock that absolutely makes my metal detector scream. I can turn the disc all the way up and the metal detector still acts like it is in all metal mode. Here's the funny thing, it sticks to a magnet.

Here is what I am sure that it is NOT:

meteorite - found in Missouri and also does not pass most of the "tests"

slag (unless I don't understand slag) - one can see metal on the outside of the rock but you can also tell that the metal is inside of the rock. This was found in the middle of the woods where there hasn't been any metal working place of any kind that I know of.

-------------------------------------------------------------------------------------------------------------------

I am guessing that it is some sort of iron ore, although it really doesn't look like any of the images of iron ore or load stone that I have found on the net. Any information is appreciated.

Doug

Hematite maybe?

No maybe about it. Either that or Goethite, which I seriously doubt.

Hematite maybe?

It sure looks like it.

aaaaaaa, old dog,

Thank you! I appreciate it very much. I'm going to mark this one as solved.

Thanks again,
Doug

I'm leaning more to Goethite. Do a streak test.
Rub a piece of the specimen against a unglazed piece of porcelain. Hematite has a reddish brown streak.

Goethite has either: yellowish brown, orange-yellow, ochre-yellow

Definite hardness and fracture differences as well

Here is a source that will put wiki in the dirt.
This is a much better source for information on rocks and minerals.

Yeah, but I was thinking to leave a minimum of damage to the specimen.
Streak colour is enough to say on this sample.

I've used Mindat, being a member there myself.

When I can get a hold of a piece of unglazed porcelain, I will do a streak test and let you know for sure.

Thanks,

The best source for an unglazed porcelain tile is the hardware store that sells flooring tiles,
the top of the tile will be glazed but the bottom won't.

Re: Magnetic rock...Please help-Hematite or Goethite

Okay, I did a streak test and it looks like dried blood. I would go with hematite because of that BUT not only is the specimen attracted to a magnet, it also shows magnetic properties. I can tie a small safety pin to a piece of string and when it gets close to the stone, it sticks very lightly to it. The magnetic properties are not strong enough to let the pin stay there. It falls right off but it still is attracted to it.

I was told by one person that hematite is not magnetic. Researching on the web, I have found sites that say both. With the weak magnetic properties, is it still a chance of hematite or do I need to look elsewhere for an answer?

Thanks,
Doug

Definitely not one of our finds in that link.


Hematite is named after the greek word for blood due to the red coloration of powdered hematite.

Hematite with magnetic properties is also called Magnetite.
when broken into needles or slivers a small sliver placed in the center of a small piece of parchment will float in a bowl and can be used as a compass.

Then it's Hematite, which is NOT magnetic.
But it can have Magnetite inside, thus making it magnetic!
