December 2019 | Explanation for the structural rise of Mjølnir’s central peak

Romain Corseri, VBPR with paper on Mjølnir Impact Crater

The effect of far-field tectonic stresses on the central peak uplift was investigated using new high-resolution P-Cable and conventional seismic reflection data. Impact-induced faults were activated by uplifted segments of the central peak up to 500 m above the platform level during one or several contractional episodes. Differential compaction, previously seen as the main deformation process, may have increased the original central peak height by only ~10 m. The mobilization of impact-shattered rocks by tectonic compression provides a new and robust explanation for the structural rise of Mjølnir’s central peak.
