摘要：Pumice has been found in over 140 archaeological
sites in Scotland (Newton 1999a). Recent research
has demonstrated that most of this pumice was
erupted, at different times, from the ice-covered
Katla Volcanic System in southern Iceland. As well
as occurring in archaeological sites and raised shorelines
in Scotland, pumice also occurs at a small
number of sites in Ireland, on raised shorelines in
Arctic Canada, at Inuit archaeological sites and
raised shorelines in western Greenland, raised
shorelines in Svalbard and Iceland and raised shorelines
and archaeological sites in Norway (Newton
1999a). The pumice found in archaeological sites in
Scotland is mainly brown, grey or black in colour and
has been retrieved from contexts dating from the
Mesolithic to Modern. Geochemical analyses of
pumice has shown that, wherever it is found, the
pumice produced by Katla can be split into three
distinct groups. These three groups can be correlated
to tephra (volcanic ash) layers and pumice found
around Katla (Larsen et al 2001).
