Test of vegetation-based surface exploration for detection of Arctic mineralizations: The deep buried Kangerluarsuk Zn-Pb-Ag anomaly.

ABSTRACT: The aim of our study was to test whether surficial geochemical techniques are applicable under arctic conditions where pedogenesis is slow or absent, and where the vegetation is arctic dwarf shrub tundra. To this end, we sampled vegetation and topsoil at a known Zn-Pb-Ag anomaly at Kangerluarsuk, northwest Greenland. This Zn-Pb-Ag mineralization surfaces in part of the test area and is deeply buried in other parts. The surface mineralization could readily be identified by element analysis of the omnipresent plant Salix glauca. The strongest signal came from the pathfinder element Tl. The target elements Pb and Ag gave only weak signals and Zn gave no signal, probably because the cellular concentration of these elements is actively regulated by the plant. The use of regulated plant m
