PRELIMINARY INVESTIGATION OF GEOCHEMICAL PROCESS RESPONSES TO POTENTIAL ENVIRONMENTAL-CHANGE IN KARKEVAGGE, NORTHERN SCANDINAVIA

Geochemical responses to potential global environmental change predict ed by Global Circulation Models (GCM's) for high altitude/latitude env ironments are being assessed for Karkevagge (literally translated as ' 'boulder valley''), Swedish Lappland on the basis of a series of stati c and dynamic field and laboratory studies. Static studies provide bas eline information on the geochemical process system, essential for und erstanding process responses to environmental change. Preliminary stud ies involve the determination of the nature and origin of lime crusts, rock varnish, and weathering rinds occurring extensively on coarse de bris in Karkevagge.
