Occurrence of pumice on raised beaches and Holocene shoreline displacement in the inner Isfjorden area, Svalbard

Finds of pumice on raised beaches in the inner Isfjorden area are reported. Pumice is abundant in two zones, and four levels can be distinguished in some areas. The highest lying level has the greatest concentration of pumice and is dated to a maximum of 6,500 years B.P. Tentative correlations with...

Description
Summary:Finds of pumice on raised beaches in the inner Isfjorden area are reported. Pumice is abundant in two zones, and four levels can be distinguished in some areas. The highest lying level has the greatest concentration of pumice and is dated to a maximum of 6,500 years B.P. Tentative correlations with pumice levels from other places in Svalbard indicate approximate ages of 6,000, 4,100, and 3,100 years for the lower levels in inner Isfjorden. A shoreline displacement curve based on the pumice levels and on 10,OOO year old driftwood is presented.
