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...

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano

Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients. Seism...
