Vallensgard Mose tephra	Plinian				doi:10.1002/jqs.990	Stratigraphic position is similar to Vedde Ash, in the middle of the Younger Dryas, but geochemistry is different. Unclear if this is a significant tephra horizon.
NAAZ I	Plinian	-10449.5	500	Marine04	doi:10.1016/j.quascirev.2006.03.001	Diffuse layer representing c. 11 ka 14C yr GS-1 ash zone containing components from I-Thol-2 (Grímsvötn), I-Rhy.1 (Katla) and I-Thol-1 (Veidivötn). It is commonly believed that the biggest contributor is the rhyolitic component of the Vedde Ash.

Several geochemical populations: RHY, INT, BAS & TAB (the 5e-Midt/TRACHY is believed to be from Jan Mayen). Wallrabe-Adams & Lackschewitz (2002) suggest either Vatnafjoll or Vestmannaeyjar may be the source.
