Evolution of the marginal zone and the forefield of the Torell, Nann and Tone glaciers in Spitsbergen

Abstract

The studies over sediments and features in the marginal zone and the forefield of the Torell, Nann and Tone glaciers (Wedel-Jarlsberg Land) in Spitsbergen enable a critical approach to the origin of inner ice-cored moraines of the Torell Glacier, considering them for the outliers of a glacier ice, enriched in a morainic material. They allow also to present a morphological evolution of this area during the Late Wòrm (= Vistulian) and the Early Holocene but first of all, since the beginning of the Little Ice Age.
