Gummite

Gummite from collection of Prague National Museum

Gummite is a yellow amorphous mixture of uranium minerals, oxides, silicates and hydrates of uranium, derived from the alteration of uraninite. It is named for its gum-like consistence.

The material was also known under various names, mostly because of different origins of the samples, including: eliasite from Elias – the name of a mine at Jáchymov, coracite – a variety from Lake Superior, pittinite, pechuran, urangummit and uranogummite.
