Abstract
Abstract The definition of the continent-ocean boundary at passive continental margins has proved to be an elusive task. Even the relatively direct method of seismic refraction experiments has yielded results that cannot always be interpreted unequivocally. Multichannel seismic reflection profiles on many passive margins have revealed the presence of remarkable suites of arcuate reflectors, dipping seaward to form a wedge-shaped structure. Their general characteristics and velocity structure suggest that they may be largely volcanic in nature, but there is no agreed upon model for their origin. Nevertheless it is generally thought that they lie at or close to the boundary between continent and ocean, and as such they are extremely important structural markers that may yield important evidence concerning the structure and evolution of passive margins.
