Yukon Whole Rock Pb-Nd-Hf-Sr and Feldspar Pb Isotope Compilation

Whole-rock and feldspar isotopic studies are used by geologists to investigate and understand geologic processes that occur deep below the earth’s surface. For example, Nd, Hf and Sr isotopic ratios in plutonic rocks can indicate juvenile (e.g., mantle) or evolved (e.g., crustal) magmatic sources. Lead isotope analyses can indicate which rocks were the source of metal (Pb) in mineral deposits.
