Physical signatures of ice advance in a Younger Dryas ice‐contact delta, Troms, northern Norway: implications for glacier‐terminus history
The depositional history of an ice‐contact delta in Sørfjorden has been reconstructed, based on two sections, 100 and 900 m long. Five major sedimentary facies have been distinguished within the delta's foreset, and their geometry and spatial organization have been mapped in the outcrops throug...
