    Author : Aron Varhelyi; [2016]
    Keywords : Tephra; Aniakchak; Holocene; Chukchi Sea;

    Abstract : 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. READ MORE
