Abstract

The AA. describe and explain a regional topographic and geomorphic expression of sub-glacial volcanism, namely that at Kverkfjöll, Iceland. This area comprises a series of parallel sub-glacially-erupted volcanic edifices, which together give excellent 3D geological exposure. These ridges are orientated north-south or along the most probable line of LGM ice margin retreat. The AA. combine topographic and geomorphic observations to explain the changing style of volcanism in space, and attribute this to the recession and downwasting of the LGM ice sheet. Their observations suggest that as the overlying ice sheet became thinner volcanic activity became more explosive. For northern Iceland, their proposed sequence of landscape development suggests 2 major glacial advances during the Holocene, at least one of which at Kverkfjöll probably coincided with volcanic activity and a jökulhlaup
