Long-term preservation of early-formed silicate reservoirs in the deep mantle: New insight from 146Sm-142Nd systematics in Hawaiian basalts

Short-lived radiogenic isotope systems provide unique constraints on the preservation of early-formed reservoirs in Earth's mantle. We present the largest high-precision μ 142 Nd dataset for a single hotspot, comprising 55 analyses of 29 shield-stage tholeiitic basalts from the H...
