This feature, named the Mjølnir structure, is 39 km in diameter and of Jurassic-Early Cretaceous age. It probably formed by the impact of an asteroid or comet, 0.7-2.5 km in diameter, into a shallow sea underlain by >5 km of sedimentary section. If the impact interpretation is correct, Mjølnir is one of the largest well-preserved craters in the errestrial record. This content is PDF only. Please click on the PDF icon to access.
