The Mohorovičić Discontinuity and the Orogenic Cycle

The following report, by Peter J. Wyllie, Department of Geochemistry and Mineralogy, Pennsylvania State University, is based on a paper presented by the author at the Second Western National Meeting of the American Geophysical Union, held at Stanford University, December 1962. A similar, more-detailed version of this paper has been published in the Journal of Geophysical Research, August 1, 1963. The version presented below includes an enlarged discussion of possible applications to the orogenic cycle; essentially the same version has also been issued as Pennsylvania State University Mineral Industries Contribution No. 62-91.
