The lithosphere-asthenosphere: Italy and surroundings
Episodes, 2003 Abstract The velocity-depth distribution of the lithosphere-asthenosphere in the Italian region and surroundings is imaged, with a lateral resolution of about 100 km, by surface wave velocity tomography and non-linear inversion. Maps of the Moho depth, of the thickness of the lithosphere and of the shear-wave velocities, down to depths of 200 km and ...

Geochemistry, Geophysics, GeosystemsSubduction zones are fundamental features of Earth's mantle convection and plate tectonics, but mantle flow and pressure around slabs are poorly understood because of the lack of direct observational constraints on subsurface flow.

Application of a Premelting Model to the Lithosphere‐Asthenosphere Boundary
Geochemistry, Geophysics, Geosystems, 2020 A seismic discontinuity known as the G‐discontinuity, which has been prevailingly detected in the oceanic mantle, is considered to provide evidence of a sharp lithosphere‐asthenosphere boundary (LAB). We investigate whether this sharp LAB is explained by

Lithosphere, asthenosphere, and perisphere [PDF]
Reviews of Geophysics, 1995 “Lithosphere” is a mechanical concept implying strength and relative permanence. Unfortunately, the term has also been applied to the surface thermal boundary layer (TBL) and a shallow enriched geochemical reservoir, features having nothing to do with strength. The “strong” lithosphere is about one half the thickness of the TBL.

New Insights Into Lithospheric Structure and Melting Beneath the Colorado Plateau
Geochemistry, Geophysics, Geosystems, 2022 The Colorado Plateau and its surroundings serve as an archetypal case to investigate the interaction of mantle melting processes and lithospheric structure.

Геодинамика и тектонофизика, 2015 The lower part of lithosphere in collisional orogens may delaminate due to density inversion between the asthenosphere and the cold thickened lithospheric mantle. Generally, standard delamination models have neglected density changes within the crust and

Геодинамика и тектонофизика, 2017 A comprehensive model for deep dynamics in Asia has been developed from the data on the evolution of melting anomalies in the context of lithospheric plate motions, interactions, orogeny, and rifting.

Tertiary-Quaternary subduction processes and related magmatism in the Alpine-Mediterranean region [PDF]
, 2006 During Tertiary to Quaternary times, convergence between Eurasia and Africa resulted in a variety of collisional orogens and different styles of subduction in the Alpine-Mediterranean region.
