The three central chapters of this work constitute an explanatory comment of the jointed Central North Atlantic reconstruction maps. In the first chapter, the model is situated relatively to other works devoted to the evolution of the Atlantic ocean, the data used and the methods followed are exposed. In th fifth chapter, we discuss some of the several implications of the model. The main characteristic of this approach is that it aims to integrate from the beginningthe major plate system constituted by: the North American, Eurasian and African plates. For each geological period, results of the detailed regional studies are referred to the evolution of the whole system and evaluated according to it. [NOT CONTROLLED OCR] |

The Jan Mayen Ridge and its southern extension were studied by means of multichannel reflection seismic profiles gathered during the Cepan 1 (Cercle Polaire Atlantique Nord) 1975 survey. These data have been interpreted with reference to the evolution of the Norwegian-Greenland Sea, which may be chronologically summarized as follows : 1) opening of the Norwegian basin from the now-extinct Aegir axis 60 myrs ago ( magnetic anomalies 23 to 20) ; 2) westward jumping of the spreading axis : this new axis (Iceland Plateau Extinct Axis) lasted between 5 D and 6 A anomaly times (24 to 18 myrs) ; 3) second westward ridge jump leading to the setting of the currently active Kolbeinsey ridge.
