ResumoIt has been suggested that the Mohorovičić discontinuity represents a change in crystal structure and not a change in chemical composition. Three objections to this view are discussed and it is concluded that it is unlikely to be correct. The objections are (1) that the stability relations are such that the continental and oceanic discontinuities cannot both have the heavier material below them; (2) that the small variation of the depth of the discontinuity with heat flow cannot be accounted for and (3) that the transition should not be sharp in a rock which is not composed of a single well defined chemical substance.
