Table 2: Sample depth (meter water equivalent, m weq.) for the Colle Gnifetti (CG) ice-core samples (upper part), sample name for the Jungfraujoch (JFJ) samples (middle part), and X-ray mineral composition with K/C for kaolinite/chlorite ratio. The symbol plus (minus) shows the abundance (absence) of minerals. The composition of fine-grained sediment (till or glaciogenic clay and silt) collected on the Grenz Glacier is reported (lower part) for comparison.
