Andersonite, Na2Ca(UO2)(CO3)3·6H2O, or hydrated sodium calcium uranyl carbonate is a rare uranium carbonate mineral that was first described in 1948. Named after Charles Alfred Anderson (1902–1990) of the United States Geological Survey, who first described the mineral species, it is found in sandstone-hosted uranium deposits. It has a high vitreous to pearly luster and is fluorescent. Andersonite specimens will usually glow a bright lemon yellow (or green with blue hints depending on the deposit) in ultraviolet light. It is commonly found as translucent small rhombohedral crystals that have angles close to 90 degrees although its crystal system is nominally trigonal. Its Mohs hardness is 2.5, with an average specific gravity of 2.8.

| - La andersonita és un mineral de la classe dels carbonats. Rep el seu nom de Charles A. Anderson (1902-1990), geòleg nord-americà de la US Geological Survey. (ca)
- La andersonita es un mineral de la clase de los carbonatos. Recibe su nombre del geólogo estadounidense Charles Alfred Anderson (1902-1990), que recolectó sus primeras muestras. (es)
- Andersonit ist ein selten vorkommendes Mineral aus der Mineralklasse der „Carbonate und Nitrate“ mit der chemischen Zusammensetzung Na2Ca[UO2|(CO3)3]·6H2O und ist damit chemisch gesehen ein wasserhaltiges Natrium-Calcium-Uranylcarbonat. Andersonit kristallisiert im trigonalen Kristallsystem und entwickelt nur selten Kristalle und tritt häufiger in Form von grüngelben, krustigen Aggregaten und Überzügen besonders auf Sandstein auf.

- L'andersonite è un minerale dell'uranio, prende il nome dal geologo statunitense Charles Alfred Anderson, che per primo la scoprì. I suoi cristalli mostrano fosforescenza se sottoposti a raggi UV. (it)

- L'andersonite, de symbole Na2Ca(UO2)(CO3)3·6H2O, ou carbonate d'uranyle de calcium et de sodium hydraté est un minéral carbonaté d'uranium rare qui a été décrit pour la première fois en 1948. Nommé d'après Charles Alfred Anderson (1902–1990) de l'Institut d'études géologiques des États-Unis, qui a été le premier à décrire l'espèce minérale, elle se trouve dans des gisements d'uranium inséré dans du grès. Elle présente un éclat vitreux élevé à nacré et est fluorescente. Les spécimens d'andersonite brillent généralement d'un jaune citron brillant à la lumière ultraviolette (ou vert avec des reflets bleus selon le gisement). (fr)
