Selenolaurite (original) (raw)

A valid IMA mineral species

Specific Gravity:

8.415 (Calculated)

The Se analogue of laurite. Unique combination of elements.

Note: most likely identical with 'Unnamed (Ru Selenide)'.

The limited data available on the composition of selenolaurite and Se-bearing laurite from four known localities indicate the presence of a miscibility gap between laurite and selenolaurite.
