The Vourinos as well as the Kamvounia ophiolite complexes yielded in origin of the serpentine-group minerals of different appearance. In this stage of laboratory studies we have concentrated on: a — filling of shear zones occurring within "basal serpentinites" of the Vourinos Complex (lizardite + chrysotile + splintery antigorite), b — the rock-forming mass of the Kamvounia massif (antigorite), c — slip-fiber "asbestos" within the Kamvounia massif (chrysotile + fibrous antigorite). While the Vourinos Complex during its geological history never reached greenschist facies conditions, the Kamvounia massif underwent metamorphic recrystallization under such conditions.
