文摘
- •
We present a more detailed aeromagnetic data set for North Greenland and the Fram Strait.
- •
The data indicate that the Kap Washington volcanic province is larger than known from onshore geological investigations.
- •
The first magnetic sea floor spreading in the Fram Strait formed already around 20 Ma, indicating an early opening of the gateway.
- •
The strength of the magnetic anomalies along the Gakkel Ridge and Lena Trough rift valleys correlate with the occurrence of peridotites.
