Lairg (Northern Scotland): evidence of Europe’s largest impact structure

New article: Michael J. Simms and Kord Ernstson (2019): A reassessment of the proposed ‘Lairg Impact Structure’ and its potential implications for the deep structure of northern Scotland. – 

Bouguer gravity residual anomaly of the Lairg proposed impact structure. A buried complex structure with an inner peak ring of 50 km diameter und derived 100 km full diameter.
Probably the source for the Stac Fada Precambrian impact ejecta deposit.
