Note how there are several generations of serpentine, among them a clear one that filled the first fractures, and a dark one (full of magnetite) that replaced the rest of the olivine.

The darker patch in the middle (and the crystal above) is ferro-eckermannite or arfvedsonite, a Na-rich amphibole.
The surrounding grey crystals are a cumulus framework of alkali feldspar.
