Cleveite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
UO2
Name:
In honour of Per Theodor Cleve (1840-1905)- Swedish chemist, mineralogist and oceanograph.
A variety of Uraninite

A REE-and Th-bearing variety of uraninite. Presence of (Y, Ce, etc.)2O3 extends to at least 10%. Related to bröggerite.
The first portions of terrestrial Helium (He) were obtained during Cleveite dissolution in sulfuric acid (Ramsey 23 March of 1895 - 27 years later of discovery of He on the Sun).
First described by Nordenskiöld (1878) from the Garta feldspar quarry, Arendal, Aust-Agder, Norway.
