A mine in a granitic pegmatite, 4,040 m. above sea level.
Consists of 3 small pegmatite dikes.
These pegmatites main minerals are quartz, plagioclase, microcline, to which is added spodumene, muscovite, biotite, beryl, lepidolite, tourmaline, sphalerite, molybdenite, uraninite, niobite, tantalite, native bismuth, bismuthinite, ferrotapiolite, manganotantalite, microlite, uranomicrolite, bismuthmicrolite, hafniferous zircon, triplite, montebrasite and other phosphates and uranium oxide minerals.
Minerals of the columbite group have varying compositions. In these cases, microlite, uranomicrolite, and occasionally bismuth-microlite often accompany the most advanced members. Ferrocolumbite was determined by chemistry and x-ray diffraction.
The crystals are centimetric to millimetric, tabular, subhedral to euhedral, with development of forms {010}, {100}, {110}, {130}, {011}, {111} in different combinations. Found in the intermediate areas, including in plagioclase, microcline or primary phosphates. Alluvial crystals are prismatic or tabular thicknesses and often have vertical striations. They are black, fragile and have a metallic to submetallic sheen.
A pegmatite deposit.

In reflected light, it is grey with very weak bireflectance; two phases can be distinguished. Electron-microprobe analysis gives the host bismutotantalite [Bi] as (Bi0.98Sb0.02)(Ta0.89Nb0.11)O4; the subsidiary phase [Bi,Sb], (Bi0.68Sb0.32)(Ta0.89Nb0.11)O4" |
