Swap List For David Aldridge

Last Updated: 12th Dec 2007

Still in the works, but here's what I've got so far...

Autunite - TN - Daybreak Mine, Mt. Kit Carson, Spokane Co., Washington, USA
-Classic Daybreak autunite. Extremely vivid green fluorescence in both LW and SW.

Autunite - TN - Dahl Mine, Mt. Kit Carson, Spokane Co., Washington, USA (Ex-Wilmer P. Walker)
-Collected by Wilmer P. Walker in 1958, resembles Daybreak stuff. Vivid green fluorescence in LW and SW.

Lueshite - Gelcap - Lueshe Mine, Kivo, Congo, Zaire
-About 5 or so black, rough xls in a gelcap of this rare mineral. TL

Gold - Gelcap - Applegate Dam, Idaho, USA
-Several small nuggets in a gelcap.


Magnesien Annabergite- TN - Lovelock Mine, Bolivia, Churchill Co., Nevada, USA (Ex-David Shannon)
-Small, white-green xls on Matrix (which looks like the massive mineral from a locality not seen in awhile.

Yttrotantalite - TN - Coats Pegmatite Mine, Petaca, Rio Arriba Co., New Mexico, USA (Self-Collected 2007)
-Massive, brown-black yttrotantalite from the Coats Pegmatite. Interesting, and rarely seen locality.


Gadolinite (Y) - Gelcap - Petrick Pegmatite, Llano Co., Texas, USA (Self-Collected 2007)
-Very rare locality, less than 5mi away from Barringer Hill (which is now submerged). Small shards in a gelcap (the Gadolinite from here is almost never found as xls).


Rheniite - Gelcap - Kudriavy Volcano, Kuril Islands, Sakhanlinskaya Oblast', Russia
-Small, slivery-red flecks on matrix. TL

Biotite, Ilmenite, REM - TN to SC - Petrick Pegmatite, Llano Co., Texas, USA (Self-Collected 2006)
Solid plates of biotite with ilmenite growing in. Unidentified REM (rare earth minerals)

Cinnabar - TN - Perry Pit, Mariposa Mine, Terlingua, Brewster Co., Texas, USA
-Mainly massive cinnabar, with a few scattered mxls. Would make a great MM! This was collected in the 1980's, by the same man who discovered Terlinguacreekite (this is also the TL for that mineral).

Calcite - TN to SC - Pinnacle Park, Dallas, Dallas Co., Texas, USA (Self-Collected 2007)
-Sharp, butterscotch to brown xls. The butterscotch fluoresce a creamy yellow, and the brown xls fluoresce orange (all under LW and/or SW).

Topaz - TN - Topaz Mt., Thomas Mt. Range, Juab Co., Utah, USA
-The classic Topaz from this locality. I also have an xl of PINK topaz from here, something rarely seen!

Fluorite - Gelcap - Topaz Mt., Thomas Mt. Range, Juab Co., Utah, USA
-Nice, purple mxls of fluorite. Odd locality

Malachite - Gelcap - Mina Ojuela Mine, Mapimi, Mexico
-I have never seen another specimen of this mineral from here. Pleasant green acicular xls in a gelcap.

Wulfenite - TN - Socorro Co., New Mexico, USA
-Vivid orange single xl, from a locality not often known for this mineral.

Vanadinite - TN - Socorro Co., New Mexico, USA
-Deep red single xl of Vanadinite from a not-so-common locality for the species.

Tyuyamunite, Selenite - Gelcap - Brewster Co., Texas, USA (Yellow MXLS on Selenite)
-Small, but sharp xls of canary-yellow tyuyamunite on a selenite matrix. Rare locality for this mineral!

Strontianite - Gelcap to TN - Mt. Bonnell, Austin, Travis Co., Texas, USA (Self-Collected 2005)
-Brilliant, snow-white (and sharp!) strontianite xls from this rarely seen locality. These make killer micromounts (see my picture gallery), and fluoresce a pale blue-green under both LW and SW.

Mimetite - Gelcap - San Pedro Corralitos, Chihuahua, Mexico
-Nice, sharp yellow xl cluster in a gelcap.

Garnet - Gelcap - Rio Grande Gorge, Taos Co., New Mexico, USA (Self-Collected 2005, 2006, and 2007)
-Small (~2mm diameter), red garnets from the Rio Grande Gorge. About half a gelcap full (would make for plenty of quality micromounts)

Staurolite - TN - Rio Grande Gorge, Taos Co., New Mexico, USA (Self-Collected 2005, 2006, and 2007)
-Single xl, collected from the stream-bed of the Rio Grande Gorge. Matrix pieces are available, however, the staurolite is usually 40-50% coated with the schist matrix.

Sphalerite - MM - Pinnacle Park, Dallas, Dallas Co., Texas, USA (Self Collected 2007)
-Small, brownish xl in clear calcite matrix. These were extracted only by carefully breaking up septarian, and even then, only 1 or two were found in every 20 or so septarians, making this an extremely scarce mineral at the locality. This locality is now under a building.
