Serpentinite Gallery


Serpentinite (ser-PEN-tinite) is a heavy, greenish metamorphic rock that forms by hydration, or serpentinization, of deep oceanic rocks. It is found on land only where pieces of oceanic plates escaped subduction and were accreted against the upper plate.

Unless otherwise indicated, these photos are from California, where serpentinite is widespread (and indeed is the official state rock).
