Abellite - description and properties of the mineral

Organic

Abellaite is a hydrocarbonate mineral found in a uranium mine, in one of the galleries of the long-abandoned Eureka deposit, in the southern Pyrenees (province of Lleida), Catalonia, Spain. Individual crystals are usually plate-like and form rather disordered aggregates.

The crystals are white or colorless, with a glassy or pearly luster, and also crumble easily. Does not fluoresce in the presence of ultraviolet light.

It is a yellowish green dimorph of an unknown lead sodium carbonate hydroxide.

Grows in association with primary minerals such as:

  • Pyrite.
  • Roscolit.
  • Uraninite.
  • Galena.
  • Coffinite.
  • sphalerite.
  • Kovellin.
  • Chalcopyrite, as well as hydrozincite, aragonite, gordaite, cheikaite, malachite, and devilline.

Named after Joan Abella i Creu, a Catalan gemologist who studied minerals from the Eureka mine for a long time and first discovered abellite.

Chemical formula of NaPb2(CO3)2(OH).
