Upper mantle structure across the Trans-European Suture Zone imaged by S-receiver functions

- Contrasting lithospheric structure east and west of the Trans-European Suture Zone.
- LAB depth is ∼90 km in the west with variations related to latest tectonic activity.
- LAB deepens to 150 km beneath TESZ and becomes indistinct beneath craton.
- MLD at 80-120 km depth beneath craton due to compositional boundary by metasomatism.
- Lehmann and mantle transition zone discontinuities imaged.
