Hello, I found this in the Oatman Arizona area, about 20 miles to the North West of Kingman Az. I don't really have a clue as to what this is. The photos have been enhanced, the rock is not wet. Your help is greatly appreciated. Thanks

It certainly is not pyrite. Pyrite is typically bronze to gold in color, doesn't form transparent crystals, and has a black streak. I'm just curious, what made you think its pyrite? Its not even close to resembling pyrite...

My best guess from just the images, the cleavages I see, and the somewhat purple color is axinite. But since you have not provided any info re: specific gravity, hardness, streak color, etc these are merely guesses.

If you are serious about identifying this, please read this topic and then reply:

http://www.mineral-forum.com/message-board/viewtopic.php?p=19487#19487

Only then will you get the experts here to answer. They tend to not give guesses based upon images alone...

Hi,
If it serves for something, I think same as Scott... But a guess that is bold....
As he says, more data, better answer

We are mineral collectors, not wizards/witches... (wish I was a wizard!)

With best wishes

The photos are 2 months old, without any testing, just means that guessing is the best we can do. This is like the others have said.

I start off with ruling in or out the common purplish minerals. It does NOT look like amethyst variety of quartz or purple colored calcite or fluorite. Again, just guessing, I favor purple colored apatite. Doing some tests might help with the identification. BOB

Yes Hwy 14. It is way difficult to identify things from photos. Relief, however, is at hand. I live here in Kingman and would be happy to look at your specimen. Please pm me and we'll set up a rime and place.
Thanks,

Ed in Kingman

Hi to everybody!
An opinion of mine: Pyrite: definitely not.
It could be a mica group mineral (muscovite, lepidolite...). Does it split in small and thin laminas? What's the hardness? Any reaction with acids?...
