They do say that we need to consume minerals for health...

I am not sure if Red Sonora is the full name of the slab, but that was what they called it on eBay. It is really beautiful in the 'flesh', so to speak.

This geode isn't quite as colourful as the red one, but it is still pretty.

The wulfenites shown here are not spectacular examples of this lead molybdenum oxide mineral. Wikipedia shows pictures of the mineral. It crystallizes in the tetragonal system. I could not find red sonora, is there a mineral name.

I don't know... I just take the name from the seller on eBay usually. I imagine it is probably sonoran *something*, but I have no idea what. It doesn't seem like an agate, and it is very fine-grained. As far as the wulfenite goes, these were the first time I had ever heard of the stuff, so I don't doubt that there are better examples.

I pretty much just collect pretty/interesting stones, when it comes down to it. I am learning some as I go, but the majority I could not identify if my life depended on it.

Thanks for the input - if you *do* find something which helps id the 'Sonora', please let me know!

Very interesting, Phil. Good pics, too--stacking sure makes a difference. :D :D

Ditto. The first two look like coconut and caramel. :-D

This is the Wikipedia image for Wulfenite, lead molybdenum oxide.
Look at the crystal habit. I think that OP's image is very fine grained Wulfenite and would have formed under very different geothermal conditions. I would also guess the Wiki image would be an unusual outcropping. Do we have any mineralogists out there.

I guess these are a lot more close-up than mine, although none of the crystals I can see on mine are square. That's interesting...

I was browsing eBay again this afternoon, and saw quite a few other wulfenite samples, but they didn't look significantly different to what I have. Always assuming that they are correctly identified, of course! Like I said, I have to go purely on what the seller calls something, although I am learning slowly, and can recognize some of the more common minerals which crop up on there.
