GEOCHEMICAL AND Pb ISOTOPIC SIGNATURE OFPEATY SEDIMENTS FROM CENTRAL-SOUTH CHILE: IDENTIFICATION OF PARTICLE SUPPLIES OVER THE HOLOCENE

Two cores from tephra rich peat soils of the Chilean Lake District were investigated for mineral source and potential anthropogenic impact using elemental geochemistry, including rare earth elements, and lead isotopes. The dominant particle source to the area are the Trumaos, which are the local and...
