Specific Gravity:
7.36 (Calculated)
Name:
In allusion to being the Ni-dominant analogue of tyrrellite.
The Ni analogue of tyrrellite. Unique combination of elements.
Nickeltyrrellite formed in response to alteration of quijarroite + hansblockite + watkinsonite + clausthalite + penroseite aggregates by oxidizing, low-T, Cu-Ni-Co-Pb-bearing fluids at a fSe2/fS2 ratio greater than unity (Förster et al. 2019).
