The contribution of locally tangential CMB-mantle flow and cold-source subducting plates to ULVZ's formation and morphology

2023
Ultra-low velocity zones (ULVZs) above the Core-Mantle Boundary (CMB) are significant structures probably connecting the lowermost mantle and the outer core. As “thin patches” of dramatically low seismic-wave velocity, they are occasionally found near the base of mantle plumes and in-or-near high seismic-wave speed regions above CMB.

The Evolution of Dense ULVZs Originating Outside LLSVPs and Implications for Dynamics at LLSVP Margins

Journal of Geophysical Research: Solid Earth
AbstractInteractions between multiple‐scale thermochemical heterogeneities in the lowermost mantle, specifically ultralow velocity zones (ULVZs) and large low shear velocity provinces (LLSVPs), are critical in lower mantle dynamics. However, the evolution of ULVZs formed outside LLSVPs has not been thoroughly explored.

Contribution of tangential CMB-mantle flow between hot mantle plumes and cold downwellings to ULVZ formation and morphology

Ultra-low velocity zones (ULVZs) above the core-mantle boundary (CMB) are observed structures that may be related to the liquid outer-core. As ”thin patches” of dramatically low seismic-wave velocity, they are occasionally found near the base of mantle plumes or in/near high seismic-wave speed regions above the CMB.
