文摘
- •
Southern Nansen Basin and Yermak Plateau sediments studied for gas geochemistry.
- •
Low concentrations of pore water methane exclude active gas seepage.
- •
δ13C of sorbed hydrocarbons suggest paleoseepage from mostly type II organic matter.
- •
2D seismic data demonstrate up to 2000 m sedimentary cover.
- •
1D-modelling and heat flow support locally oil window maturity of Eocene sediments.
