Abstract

In order to better constrain the Cenozoic evolution of the Norwegian-Greenland Sea and contiguous margins, a new aeromagnetic data (JAS-05 survey) was acquired in the Eastern part of the Jan Mayen Fracture Zone during autumn 2005. We present preliminary results and interpretation of this survey. The main faults, structure and magnetic anomalies have been re-interpreted using a systematic comparison between bathymetry, gravity, magnetic patterns and available seismic data. Magnetic chrons have been identified and has been used to provide accurate Cenozoic ages for the oceanic basement and overlying sedimentary sequences, identified on seismic. The new magnetic survey and integrated study allow us to discuss the tectonic and magmatic evolution of the Jan Mayen Fracture Zone and its geodynamic implications
