Summary Rayleigh and Love wave group, and phase velocity dispersion has been determined for two profiles crossing the interior of Greenland. It was found that the dispersion is similar on the two profiles. The observed dispersion is only a little different from the Canadian Shield dispersion. The observations have been compared with theoretical model dispersion curves. A model G‐62 has been developed for the Greenlandic Shield. It is similar to the model for the Canadian Shield. The depth to the Mohorovičić discontinuity appears to be a little greater than in Canada.
