	<abstract content_type="html">The comparison of two shallow ice cores recovered in 1999 and 2000 from the
same place on Chimborazo summit glacier revealed the influence of the
coincident Tungurahua volcanic eruption on their stable isotope and chemical
records. The surface snow melting and water percolation induced from the ash
deposition caused a preferential elution and re-localization of certain
ionic species, while the stable isotope records were not very affected.
Additionally, the comparison of the ionic amount and some selected ratios
preserved along the ice core column reports under which processes the
chemical species are introduced in the snow pack, as snow flake condensation
nuclei, by atmospheric scavenging or by dry deposition. This preliminary
study is essential for the interpretation of the deep Chimborazo ice core,
or for other sites where surrounding volcanic activity may disturb the
glaciochemical records.</abstract>
