Extending the known distribution of the Vedde Ash into Siberia : occurrence in lake sediments from the Timan Ridge and the Ural Mountains, northern Russia
Tephra shards from the Vedde Ash eruption have been identified in two lakes from northwestern Russia and the Polar Ural Mountains. This is the most distal and easternmost occurrence of this regional tephra marker horizon found so far and it extends the area of the Vedde Ash tephra more than 1700 km...

| description | Tephra shards from the Vedde Ash eruption have been identified in two lakes from northwestern Russia and the Polar Ural Mountains. This is the most distal and easternmost occurrence of this regional tephra marker horizon found so far and it extends the area of the Vedde Ash tephra more than 1700 km further east than previously documented. This means that particles the size of fine sand have travelled more than 4000 km from the Katla volcano source, south Iceland. These findings offer a new possibility to correlate archives over a very long distance in the time period around the Younger Dryas. |

This work was financially supported by TheResearch Council of Norway and is a contribution to the project‘Climate History along the Arctic Seaboard of Eurasia’ (CHASE)(NRC 255415). The coring fieldwork was carried out in 2000 at LakeYamozero and 2009 at Lake Bolshoye Shchuchye during the formerresearch projects ‘Paleo Environment and Climate History of theRussian Arctic’ (PECHORA II) and ‘The Ice Age Development andHuman Settlement in Northern Eurasia’ (ICEHUS) funded by theResearch Council of Norway (NRC 167131 and NRC 176176048). M.Henriksen (Universityof Bergen)supplied the core material selected forthe Lake Yamozero cryptotephra detection work. The Lake Yamozerogeochemical analysis was conducted with funding from the NERCRAPID Climate Change thematic programme, project NE/C509158/1‘Precise chronology of the timing of changes in behaviour of the NorthAtlantic THC and their forcing effects, 16–8kaBP’. 2021-03-23T01:32:58Z 2021-03-23T01:32:58Z 2019 Journal Article Haflidason, H., Regnéll, C., Pyne-O'Donnell, S. & Svendsen, J.
