Abstract

The origin of some hydrocarbon bearing sedimentary basins of the world can be perfectly linked to the effect of thermal anomalies, which are either periodically or episodically active and are located presumably at stable positions within the Earth mantle, above which the lithospheric plates migrated during their continental drift. Volcanism and magmatism during the initial phase of the basin development, thermal metamorphosis within the lower crust and the interaction with isostatic subsidence are processes, which accompanied the evolution of these sedimentary basins. Analyses of metamorphic processes, of potential field anomalies, of temperature fields, and of histories of subsidence have been integrated into a model that especially explains the development of the North German Permian Basin. The model might be applicable to some other known basin structures. It is different from the conventional basin forming theories. Extension and rift processes may be processes of secondary order. The West Siberia Basin, the Sichuan Basin, the Dniepr-Donets Basin, and the North Sea Basin are analysed together with the North German Permian Basin.
