Late Mesozoic-Cenozoic tectono-stratigraphic evolution of the Vesterålen margin, offshore northern Norway

Main aims/objectives: The main purpose of this thesis is to study the structural styles and geologic evolution of the Vesterålen margin, offshore northern Norway.

Data:

• 2D seismic data (selected profiles from surveys: LO-86/87/88/89; NPD-LOF1-07/08; TGS: N6-92-RE00 & N7-92/N7-I00, LOO00RE, RB-93, UH-94-RE-00, parts of Atlantic Margin Revival; IKU-LO-90 etc).

• 3D seismic data: NPD-LOF1-09

• Well data (well-tops: IKU shallow boreholes: 6710/03-U-01, 6710/03-U-02, 6814/04-U-01).

• Gravity anomaly field: courtesy to TGS [alternatively: 2x2 km onshore-offshore NGU grid (Skilbrei et al., 2000)].

• Magnetic anomaly field: courtesy to TGS [alternatively: 2x2 km RAS-03 NGU grid or eventually 5x5 km onshore-offshore grid (Verhoef et al., 1996)].

• Bathymetry: 1x1 min (or higher resolution) gridded GEBCO bathymetry (Jakobsson et al., 2000).

Methods/tools:
Seismic interpretation using Petrel

[(optional) Modelling: potential field (gravity; magnetics optional) modelling using GMSYS]

[(optional) Modelling: backstripping and structural restoration (using 2DMove)]

Work plan:

- Interpretation of regional 2D seismic lines

- Seismic to well ties, stratigraphic calibration

- Detailed interpretation of seismic data

- Structural analysis: timing and style of faulting

- Margin segmentation and basin architecture

- Synthesis: basin/margin evolution and regional (along margin and conjugate) implications; role of along-margin transfer zones
