Abstract
Our approach consists in 1. constraining the evolution of rifted shelf with the age of magnetic chrons in the Eurasia basin, and interpret a break-up unconformity that correlates in time with the emplacement of the oldest oceanic crust in the Eurasia Basin 2. Differentiate on seismic the sedimentation patterns from greenhouse conditions from those of icehouse conditions, as documented by the ACEX well drilled on Lomonossov Ridge. 3. Correlate nearshore structural cross sections, calibrated on deep wells with shallow water seismic data 4. Compare the basement structure prepared from magnetic records with the acoustic basement interpreted from seismic data 5. Calibrate older seismic data against newer, acquired with long-streamer, to better define the base of the rift infill and its relation to regional structural styles existing from Verkoyansk to Annabar.
