Determining the composition of Earth's lower mantle, which constitutes almost half of its total
volume, has been a central goal in the Earth sciences for more than a century given the …

Abstract The Choiyoi Magmatic Province represents a major episode of silicic magmatism in
southwestern Pangea in the mid-Permian-Triassic, the origin of which remains intensely …

Abstract The Southern Atlantic-Southwest Indian ridges (SASWIR) host mid-ocean ridge
basalts with a residual subduction-related geochemical fingerprint (ie, a ghost-arc signature) …

The nature of compositional heterogeneity in Earth's lower mantle remains a long-standing
puzzle that can inform about the long-term thermochemical evolution and dynamics of our …

The formation and preservation of compositional heterogeneities inside the Earth affect
mantle convection patterns globally and control the long-term evolution of geochemical …

The Pacific large low-shear-velocity province (LLSVP), as revealed by cluster analysis of
global tomographic models, hosts multiple internal anomalies, including a notable gap …

Iron partitioning among the main lower mantle phases, bridgmanite (Bm) and ferropericlase
(Fp), has non‐monotonic behavior owing to the high‐spin to low‐spin crossover in ferrous …

The elastic bulk modulus softening of (Mg, Fe) O ferropericlase across the iron spin
crossover induces dramatic changes in its physical properties, including seismic P …

Three-dimensional models of Earth's seismic structure can be used to identify temperature-
dependent phenomena, including mineralogical phase and spin transformations, that are …

Individual sinking slabs present markedly different geometries between 410 and 660 km
depths, from vertical slabs penetrating the lower mantle to slabs stagnating above the lower …
