Closeup view about 30 cm × 20 cm (11.8 in × 7.9 in). Serpentinite is a rock composed predominantly of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake.Serpentinite. Serpentinite is a soft, compact, pale green to greenish-black rock consisting wholly or largely of serpentine minerals—antigorite, chrysotile, or lizardite (allomorphs of Mg 3 Si 2 O 5 (OH) 4 ). These minerals are usually produced by the hydrous alteration of olivine, orthopyroxene, and, to a lesser extent, clinopyroxene.
