Sediment routing & detrital zircon age dating in the Middle Jurassic Garn & Pelion Formations on the Mid-Norwegian shelf & East Greenland
Hovedinnhold
Project description
The Middle Jurassic Garn Formation in the Norwegian Sea is composed predominantly of relatively homogeneous sandstones. However, their distribution, reservoir architecture, and reservoir quality remain poorly constrained. Time-equivalent and broadly facies-equivalent sandstones of the Pelion Formation are exposed on East Greenland, but the extent to which these outcrops can inform subsurface interpretations of the Garn Formation is not well established.
Improved insights into sediment routing systems, sediment provenance, and proximal–distal relationships for both the Garn and its East Greenland equivalents are essential for resolving these uncertainties.
This project will involve U-Pb geochronological analysis of detrital zircon grains from both the Garn and Pelion formations to reconstruct sediment pathways and source regions. In addition, selected cores from the Garn Formation will be described and logged in detail. The overarching objective is to develop a refined model for sediment distribution and routing in the Norwegian–Greenland Seaway during the Middle Jurassic.
