Abstract
THE great volume of modern refraction data has revealed the inadequacy of what was, until recently, the usual method of interpretation, that is, the process of fitting a series of straight lines to the travel-time observations, and of interpreting the resulting diagram in terms of a plane-stratified crustal model. Sometimes the artificiality of such models is revealed within the area of a single survey. On other occasions, discrepancies have appeared when structures postulated to explain data from neighbouring areas have failed to agree at the survey boundary.
