Microminerals and Micromounts: A thru L- generally require magnification. Matrix is usually TN (thumbnail) or smaller.
Update March 21, 2008: We apologize for the long time of not updating this page. We are planning to upload new specimens in the next week or so. We have quite a few microminerals available; if you're looking for something specific please don't hesitate to ask.
For an explanation of abbreviations used, please see our guide to mineral sizes.
Anatase - Holmstrand, Norway. Several black, shiny, sharp, bipyramidyal anatase xtls. Also some very tiny yellow xtls of Parisite-(Ce). Best at 20x or higher. Unmounted.
#M271.... $5.00
Azurite - Kelly Mine, Magdalena, NM. Blue, lustrous micro xtls in limonitic matrix. With minor malachite, etc. Best at 20x or higher. Unmounted.
#M278 ... $3.50
Bastnaesite-(Ce) - Poudrette Quarry, Mont Sainte-Hilaire,
Quebec, Canada. Greenish-grey micaceous flakes & masses on matrix.
At least one (shown) is a well-formed hexagon.Sugg. 30x or better mag.
Puttied in a "Perky" box with printed label. #M246 ... $5.00
Calaverite and/or Krennerite (AuTe2) - Cresson Mine, Cripple Creek, Colorado. Gold telluride. Striated, metallic, subhedral xtln., in gray matrix. Sugg. 20x or better mag.
#M276 ... $6.00
Hauyne - Niedermendig, Eifel, Germany.
Sky blue anh. xtln. grains in matrix. One seems to have an actual
xtl face. Hauyne, like sodalite, doesn't usually form well-defined
xtls. It most often appears as vitreous blobs. #M251... SOLD
Hematite, Quartz, and ? - Nine Mile Pluton,
Wausau Complex, Marathon County, Wisconsin. The dark, silvery mirror-like
flakes are hematite. I'm not entirely certain about the thicker,
tabular xtls near the quartz (tantalite / columbite?). The pegmatites
of the Nine Mile Pluton contain quite a variety including several rare-earth
minerals. There is a paper by A. Falster et al. that details the minerals of
the Wausau Complex, with SEM photos.Puttied in a prepared M511 box w/ label.
#M256 ...Sold
Garronite - Galboly, Garron Escarpment, County Antrim, Northern Ireland. White, fibrous, crystalline masses. Not very exciting to look at, but an unusual species and also the type locality for this mineral.
#M273 ... $3.00
Heulandite - Veneto, Italy. Small, shiny, transparent cluster of xtls with a faint yellowish cast. Visible at 10x or higher. Unmounted.
#M272 .... $4.00
Ilmenite - Tosca Quarry, Varsi, Parma, Italy. Tiny, sharp, lustrous micro xtl in a cavity in matrix. Vis. at 10x, but higher mag. suggested.
