Geochronology of the Ophiolites

  • M. Delaloye
Conference paper


It would be useful to define precisely at the outset the term ophiolite, for it has had various meanings over the course of time. Although, used by Brongniart, Fouquet, Michel-Levy and Dana, one should start with the concept introduced by Steinmann in 1927 to cover the association of peridotites, gabbroes, diabases and spillites, the existence of a link. between these different rock types has led to the word ophiolite being used more as a descriptive than a genetic term. The Penrose Conference of 1972 proposed a more restrictive definition, which, unfortunately, has not been generally accepted.
