Summary The Troodos igneous complex of Cyprus is an ophiolite body composed of ultramafics, gabbros, dolerites and pillow lavas. Seismic velocities measured in these rocks were expected to be similar to those in the layers under the deep ocean. Seismic experiments made in the field in individual rock types revealed only low velocities typical of deep sea layer 2. We suggest that the low velocities are due to high porosity in the shattered rocks.
