In the USA Gallery we present some minerals from districts and localities all over the country from Maine to California. In Page 1 you can browse through nice calcites, old millerites, wulfenites, dioptases, elbaites and others while Page 2 is devoted to specimens from Mississippi Valley-type deposits as the Elmwood-Gordonsville District in Tennessee, the Viburnum Trend in Missouri and the Illinois Fluorspar District.

 

WUSA-14/15 - Analcime

Paterson, Passaic Co. (New Jersey, USA)

Cluster of white, opaque trapezohedral crystals of analcime to about 1.8 cm. across on a thin slab of matrix. The present crystals are quite clean of damage, there are however two crystals lacking as can be seen in the pictures. Previously at the Mackay School of Mines, University of Nevada, and Steve Pullman collections.

WUSA-10/3 - Wavellite

De Linde Mine, Dug Hill, Avant, Garland Co. (Arkansas, USA)

A brecciated chert-like matrix with vugs coated by wavellite spheres to about 6 mm. across. The spheres show a nice apple-green color and typical radiating structures when broken open and are coated by an outer light green layer. There are small areas coated by light green to colorless individual microcrystals of wavellite. Quite different from the classic wavellites from the region.

WUSA-10/4 - Wavellite

De Linde Mine, Dug Hill, Avant, Garland Co. (Arkansas, USA)

Brecciated matrix with coatings of green spheres of wavellite to about 8 mm. across showing radiating structures in some areas. The surface of the spheres shows lustrous crystal faces. There are small areas of matrix coated by light green to colorless individual microcrystals of wavellite.

8.1x6x5.5 - 55 €

 

 

WUSA-10/33 - Wavellite

De Linde Mine, Dug Hill, Avant, Garland Co. (Arkansas, USA)

Bright apple-green spherical aggregates of wavellite showing radiating structures when broken open coat surfaces in a brecciated black chert-like matrix. The first layer of wavellite resting directly on the matrix is made of light green individual microcrystals of wavellite. Color of wavellite and matrix make this specimen quite unusual and different from the others in this group.

WUSA-10/37 - Wavellite

De Linde Mine, Dug Hill, Avant, Garland Co. (Arkansas, USA)

De Linde Mine, Dug Hill, Avant, Garland Co. (Arkansas, USA)

Brecciated matrix with coatings of dark green spheres of wavellite to about 1 cm. across showing radiating structures when broken open. The surface of the spheres shows lustrous crystal faces. The matrix is also coated by light green to colorless individual microcrystals of wavellite in some surfaces.

WUSA-SW/100 - Quartz (faden)

Mt. Ida, Montgomery Co. (Arkansas, USA)

Matrixless group of several "faden" structures formed by transparent to translucent tabular quartz crystals making a strange arched specimen. Minor nicks here and there.

WUSA-SW/272 - Quartz

Bennett Quarry, Buckfield, Oxford Co. (Maine, USA)

Floater tabular biterminated crystal of translucent whitish quartz with some areas coated by yellowish cookeite. Very little damage at bottom termination difficult to appreciate.

10x5.8x1.3 - 30 €

 

 

WUSA-SW/271 - Quartz

Bennett Quarry, Buckfield, Oxford Co. (Maine, USA)

Floater tabular biterminated crystal of translucent whitish quartz. Just a tiny nick at one termination difficult to appreciate.

10.5x4x1.5 - 30 €

 

 

WUSA-13/8 - Wulfenite

Red Cloud Mine, Trigo Mtns., La Paz Co. (Arizona, USA)

Several square flat crystals of reddish orange wulfenite to 0.8x0.6 cm. on a calcite-rich matrix. They are tabular crystals with the edges bevelled by bypiramids, on the smallest crystals the habit becomes more bypiramidal. Undamaged. From the 1996 findings.

6.4x4.8x3.2 - 80 €

 

 

WUSA-05/61 - Copper

Ajo, Pima Co. (Arizona, USA)

Large heavy mass of pure metallic copper with numerous distorted crystals to about 2.5 cm. across as well as skeletal growths in some areas. Small pieces of matrix attached as seen in the pictures. Presents some pitted surfaces which may indicate that the specimen has been perhaps etched at some moment in the past to eliminate patina (but I am not sure at all about that, the pitted surfaces may also be natural). Undamaged. Nice and interesting old specimen from the collection of the Estate of Esmond Bradley Martin, Knole, Old Westbury, New York.
