Trace element chemistry for samples from the Adirondacks, New York, USA, analyzed for cosmogenic Chlorine-36

Cl is calculated using isotope dilution based on AMS data and the methods of Faure (1983).Trace elements were analyzed by ICP-MS with detection limits (ppm) as follows: 10 for B, Cr, Li; 0.1 for Sm, Th; 0.05 for Gd, U.
