Abstract

Agglutinate deposits, plastic scoriae, and blocks ejected as part of recent parasitic activity associated with Beerenberg volcano on Jan Mayen island in the north Atlantic Ocean, make up about half of the pyroclastics in the Nordkapp (North Cape) region. These deposits are described and it is proposed to call the widespread areas agglutinate fields. Two types of agglutinate are differentiated--one composed of pancakes (flattened bombs) and bombs, the other of driblets. The difference between the two types seems to be a matter of distance from the source fissure. The formation of agglutinate rather than agglomerate is attributed to eruption occurring as a gentle fountaining rather than a more violent one that would produce bombs.
