In particular, in the vicinity of the 40-km-diameter crater three erosive/depositional gullies are identified cutting through the rim wall faults. The gullies have meandering patterns and reach 70 m depth, 5 km width, and 25 km length. Mjølnir lacks a prominent, raised rim wall an

The age of impact is currently regarded as Bajocian (Middle Jurassic), on the basis of palynostratigraphy of crater lake sediments, but there is no significant extinction in the Bajocian. Earlier K-Ar age determinations of impactites compared with a current

The differences between the impact craters that result on such bodies, compared to those on more traditional ice targets (effectively large, well consolidated, semi-infinite ice surfaces) is discussed with particular reference to the impact on a co

To this end, the two-stage light gas gun at the University of Kent has been used to fire bacteria-laden projectiles, at velocities of approximately 5 km s., onto semi-solid nutrient medium, and solid a
