Dʺ structures beneath the East China Sea resolved by P‐wave slowness anomalies

J Li, D Tian, D Sun, P Tong - Journal of Geophysical Research …, 2024 - Wiley Online Library
The Dʺ layer, defined as 200–400 km in the lowermost mantle, is a thermal and chemical
boundary layer between the solid silicate mantle and the liquid outer core. Deciphering the …

Localized ultra‐low velocity zone as a strong scatterer at the core‐mantle boundary beneath central America

J Li, D Sun, D Tian - Journal of Geophysical Research: Solid …, 2024 - Wiley Online Library
Small‐scale scatterers in the lower mantle contain key information on the recycling process
in the whole mantle. Resolving the fine structures of these scatterers is crucial for …
