Previous studies have documented the presence of ultra-low-velocity-zones (ULVZs) at the
base of the mantle, through observations of body wave complexities. Geometrically their …

Ultralow velocity zones (ULVZs) and seismic anisotropy are both commonly detected in the
lowermost mantle at the edges of the two antipodal large low velocity provinces (LLVPs) …

We use core reflected ScS waves sensitive to a broad region of the core-mantle boundary
beneath Hawaii to create the first high-resolution map of the Hawaiian ultralow-velocity zone …

At the core‐mantle boundary, most observed ultralow velocity zones (ULVZs) cluster along
the edges of the large low shear velocity provinces (LLSVPs) and provide key information on …

Thin patches with ultralow velocities have been proposed to exist at the core‐mantle
boundary (CMB). The detection and mapping of ultralow velocity zones (ULVZs) are difficult …

Ultra-low velocity zones (ULVZs) are localized small-scale patches with extreme physical
properties at the core-mantle boundary that often gather at the margins of Large Low …

Mantle flow in Earth's interior has been inferred from a variety of geo-disciplines. Two
continental-scale, nearly antipodal, large low shear velocity provinces (LLSVPs) at the base …

The lowermost mantle right above the core-mantle boundary is highly heterogeneous
containing multiple poorly understood seismic features. The smallest but most extreme …

The core‐reflected phase ScP is a sensitive probe of the properties of an ultralow velocity
zone (ULVZ) at the base of the mantle. In synthetic experiments, a ULVZ with large …

Abstract The Large Low Shear Velocity Provinces (LLSVPs) in the lower mantle represent
volumetrically significant thermal or chemical or thermo-chemical heterogeneities. Their …
