Radiogenic 182W and 142Nd anomalies in 2.7 Ga old basalts indicate long-term preservation of early mantle heterogeneities

Description

Major and trace element abundances, 187Re-187Os, 147Sm-143Nd, and 176Lu-176Hf for Theo's Flow tholeiites and Pyke Hill komatiites. W isotopic compositions for Theo's Flow tholeiites. 142Nd-143Nd model ages for mantle differentiation.
