Reductively altered Serpentinite

Reductive alteration + Serpentinization

Required Geological Setting

Accretionary complexes


Native element and alloy minerals formed by reaction of magnetite in serpentinite with reductive and hyperalkaline fluids produced by serpentinization. The passes of this reductive fluids are oberved as veins in serpentinite, and iron and Fe-Ni alloys are produced in the veins. Iron and Fe-Ni alloys exhibit rounded shape.
