Hey guys! New to the forums and rock hounding in general, I just moved to Arizona and went hiking in the Pinaleno Mountains today (big mistake to do when it's 105 out, but I drank water like no tommorow), and I found a rock that caught my eye. It didn't set off my metal detector but it's very magnetic... attached is a photo if anyone can help me ID this, that'd be great :)

Hard to tell from the photo, but looks like the shiny material is common mica. If you poke it with something like a knife or fork time does it "shatter" and produce flakes?

The magnetism indicates ferrous metal or magnetite. The pic is just too dark to get a good read on it, but some expert around here will certainly chime in, I'm sure.

Welcome to the forums. Let me know if you ever want to go out beeping.

Impossible to tell from the photo. I suggest you do a streak test first. Scratch the stone across a piece of unglazed porcelain. You can use the underside of the lid on the water tank of your toilet.

Next- you can do a hardness test.

If you knew the specific location- it would help.

Post the results here and we'll see if we can narrow it down. A better photo would help also....

Thanks so much for the help guys! I plan on being a rock hound for the time I am out here, which is till October! I'm probally going to the mule mountains this weekend to look for Turquoise and/or small gold. Here are some more pictures and as I attempt to do tests, I will post the results. Tried a variety of lighting for the pictures.

Steak test gave like a orange/gold color

You should streak it some more in the same place. That was probably just a surface streak and not an interior one. If it's the same, it could be limonite,hematite or a combination of those two and other iron minerals.

I believe that it may be a combination of a couple minerals. I`ve known Hematite to sometimes carry very little magnetism. It may be a micacious schist that carries an iron mineral ? Hmmmm :hmmmmm:

Hi AZGG , Those specimens are important to you and thats what matters. Looks like a bunch of quartz for the most part ,and maybe some Basalt or rhyolite... Best of luck out there !
