Last year at Tucson, I acquired a dark blue botryoidal plumbogummite from the Yangshuo Mine. I searched hard for a specimen of the other habit, where the plumbogummite forms a pseudomorph of pyromorphite, but was unable to find an undamaged miniature. This year I was happy to find the following little group to go with the other specimen.


Plumbogummite ps. pyromorphite - Yangshuo Mine.jpg
 Mineral: Plumbogummite ps. after pyromorphite
 Locality:
Yangshuo Mine, Yangshuo, Guilin Prefecture, Guangxi Zhuang Autonomous Region, China
 Dimensions: 3.2 x 4.7 cm
 Description:
Pale blue plumbogummite forming a near complete replacement of green pyromorphite crystals.

It's not every day when one finds a nice mineral specimen from Texas, so I was happy to add the following piece to the few others in our collection of minerals from the Lone Star State.


Marcasite - Temple, Texas.jpg
 Mineral: Marcasite
 Locality:
Temple, Bell County, Texas, USA
 Dimensions: 5.7 x 5.8 cm
 Description:
Razor-sharp, lustrous, silvery-gold bladed marcasite crystals from a seldom seen locality. These marcasites were collected as they weathered out of limestone blocks under the Highway 36 bridge over Cedar Creek. The blocks originated from a nearby quarry where there is no access.

Beautiful and interesting aquamarine, Michael. Do I see tubes in this specimen?

Hello to Laura.

Thanks Don. Although the photo may give the appearance of tubes, there are none. What you are seeing is very fine surface striations. I suppose that these may be related to the dissolution of the termination. I have not observed this feature in any other aquas that I have looked at, and that difference is what drew me this particular specimen.

Regards,
Michael

When I first looked at this specimen, I thought it was another Ojuela Mine aurichalcite. When I looked at the label, it immediately became more interesting.

Campiglia Marittima, Campigliese, Livorno Province, Toscana, Italy
 Dimensions: 7.5 x 8.6 cm
 Description:

I just received word from Jordi that a recent analysis in Germany showed these 'mimetites' from the Gowd Mine to be vanadinite. Since these two minerals form a series, until I hear somethiing more definitive, I have labeled this specimen as Mimetite-Vanadinite series.


Mimetite - Gowd Mine, Iran.jpg
 Mineral: Mimetite-Vanadinite series
 Locality:
Gowd Mine, Anarak District, Nain, Isfahan Province, Iran
 Dimensions: 6.8 x 9.1 cm
 Description:
Prismatic yellow-orange hexagonal crystals to 0.5 cm scattered over a quartz and calcite matrix.

Many thanks Pierre. I have never heard the term 'harlequin' quartz before, but it is certainly an apt description.

Thanks Bob. Tobi - the similarity of these 2 specimens is quite remarkable. Always nice to see another specimen from a collector who loves galena as much as myself. Thanks for showing yours.
