Whatzit?

[rogruth]

Looks almost like an old open pit copper mine that is no longer in use like at Ajo.
I can't really tell if it is a depression or lines on something.

Margaritasite

I don't know if margaritasite is mined around Tucson or not but the whatzit is not margaritasite.

I see what you see Roger but the whatzit is in a landscaping rock. Rocks blasted from the open pit mines that are not suitable for copper recovery can be sold as interesting landscaping rocks.

Wayne,
Does this stuff come from open pit copper mines?

[webenda]

Not necessarily Roger. That rock came from an open pit copper mine but azurite, the whatzit mineral, and rocks can be found in underground copper mines also.

Well, that turned out to be as blue as expected:

OK, Azurite is blue but what is the ochre colored whatzit mineral?

...what is the ochre colored whatzit mineral?

My little computer says iron(III) oxide-hydroxide, or limonite, gives a yellow color.

Are you showing us hematite Robert? The ochre colored mineral is not hematite.

Indeed, it is limonite, Roy. Limonite is the source of ochre pigment. Depending on the iron's oxidation state it can be yellow (ochre), red (burnt sienna) or brown (burnt umber).
