When I acquired this specimen at the recent Denver Show it was labelled as Hematite pseudo after Magnetite. Although 'martite' does occur at this locality, I decided to do a simple streak test today. I tested several areas of the specimen and the streak was uniformly grey-black, so there is no hematite, just pure magnetite.

| Locality: | | Iron Springs District, Iron County, Utah, USA | |

| Dimensions: | 4.0 x 3.5 cm |

I am not a species collector per se, but I decided to add this specimen to the collection for several reasons. (1) It was collected by someone that I knew and admired, (2) it was from the Type Locality, and (3) it is an uncommon mineral that I had never heard of, so it represented an opportunity to learn about it and the location it came from.
Schoderite is a hydrous aluminum phosphovanadate named for William P. Schoder, a longtime research chemist with Union Carbide Nuclear Company, for his outstanding contributions to the metallurgy of vanadium. Although the VanNavSan Claim is the Type Locality, Schoderite probably reaches it best development at the Union Carbide Mine, in Wilson Springs, Garland County, Arkansas, where it forms attractive, bladed microcrystals. I will be on the lookout for one of these :>)
| Mineral: | Schoderite |
| Locality: | | VanNavSan Claim, Fish Creek Range, Gibellini District, Eureka County, Nevada, USA | |
|
| Dimensions: | 7.7 x 5.0 cm |
| Description: |
| Yellow-orange microcrystals of schoderite covering the top surface of a friable light brown matrix. Collected from the Type Locality by David Shannon, July 1995. |

Wonderful Morenci specimen! I'm not that much into azurite as many other collectors but I like these specimens from Morenci with the colourful contrast of blue on green. The only azurite specimen in my collection is also one from Morenci ;-)
Very nice, Michael!

Thanks Tobi,
Each of the other Morenci specimens in the collection are quite different. The other specimens are either azurite or malachite alone, so I was happy to acquire this combination specimen.

Nice specimen Michael, not easy to get such well-developed and long-prismatic ROSE quartzes!
