Ni(alpha)

Formula : Ni

Family: 
Space group: 
Isometric - Hexoctahedral H-M Symbol (4/m 3 2/m) Space Group: F m3m
Dana class: 
1.1.11.5 (1) Native Elements (1.1) with metallic elements other than the platinum group (1.1.11) Iron-Nickel group
High temperature: 
In the low-temperature deposits native nickel is associated with sulfides. It needs a reduced environment.
Geological context: 
In serpentinized ultramafic rocks as a result of low-temperature hydrothermal activity.
