Summary
Variations in density in the basaltic layer and the upper mantle are postulated as being due to mineral conversions as result of high temperature and pressure variations. This theory has been developed in order to explain the elevation of mountain chains, median ocean rises and deep sea trenches as being caused by compressional and tensional stressfields.
Zusammenfassung
Es wird angenommen, daß Dichte-Änderungen in der Basalt-Schale und dem oberen Teile des Erdmantels von Mineralumwandlungen infolge hoher Temperatur- und Druck-Änderungen herrühren. Diese Theorie wird ausgebaut, um die Hebung von Kettengebirgen und ozeanischen Rücken und die Bildung von Tiefseegräben auf Grund von Zug- und Druckspannungs-Feldem zu erklären.
