Abstract
Ocean-floor metamorphism, which overprints the pseudo-stratigraphy of ophiolite complexes in southern Chile, is best explained by a combination of hydrothermal and contact metamorphism associated with igneous activity at a spreading centre. Such metamorphism may be more important than igneous processes in producing the observed seismic layering and magnetic properties of the ocean floor.
