Compositional heterogeneity in the mantle transition zone
Earth's mantle transition zone (MTZ) is characterized by several sharp increases in seismic
wave speed between~ 300 km and~ 850 km depth. These seismic discontinuities are …

Cratonic crust illuminated by global gravity gradient inversion
P Haas, J Ebbing, W Szwillus - Gondwana Research, 2023 - Elsevier
We present a global study of the crustal structure with emphasis on the twelve main cratons
of the earth. In an inverse scheme, satellite gravity gradient data from the GOCE mission are …

A complex mantle plume head below East Africa‐Arabia shaped by the lithosphere‐asthenosphere boundary topography
Hot plumes rising from Earth's deep mantle are thought to cause uplift, rifting and large
igneous province (LIP) emplacement. LIP volcanism in continents often spans tens of Ma …

Defining continental lithosphere as a layer with abundant frozen‐in structures that scatter seismic waves
We investigate the structure of the continental lithosphere by combining two approaches: a
systematic survey of abrupt changes in seismic properties detected by P‐to‐S converted …
