3. 2. The late Holoce 14C reservoir age in the Chukchi Sea as inferred from tephra in marine sediments

   Kandidat-uppsats, Stockholms universitet/Institutionen för geologiska vetenskaper

   Författare :Aron Varhelyi; [2016]
   Nyckelord :Tephra; Aniakchak; Holocene; Chukchi Sea;

   Sammanfattning : Volcanic ash, or tephra, blankets the local and regional landscape following a volcanic eruption. If this ash layer is preserved and identified, it can act as a time synchronous marker bed (isochron) for correlation between marine, terrestrial, glacial and lacustrine deposits. LÄS MER
