The Global Crust and Mantle Gravity Disturbances and Their Implications on Mantle Structure and Dynamics
The gravity anomalies reflect density perturbations at different depths, which control the physical state and dynamics of the lithosphere and...
-
Longitudinal structure of Earth’s magnetic field controlled by lower mantle heat flow
Thermal interactions between Earth’s core and mantle provide the power that maintains the geomagnetic field. However, the effect of these...

Energetics of Mantle Convection
Mantle convection and the production of the great tectonic plates described in Chap. 1 have energy flow...

Arc Tectonic Elements and Upper Mantle Structure of Central and Southeast Asia: Seismic Tomography and Seismicity Data
AbstractAnalysis of the upper mantle plumes spatial distribution in the inner part of the Sunda arc shows a number of plume bodies interrupting the...

Earth’s mantle composition revealed by mantle plumes
Mantle plumes originate at depths near the core−mantle boundary (~2,800 km). As such, they provide invaluable information about the composition of...

Structure of the Upper Mantle Beneath Northern Eurasia Derived from Russian Deep-Seismic PNE Profiles
From 1968 until 1990, Russian scientists carried out an intensive program of deep seismic sounding across the territory of the former Soviet Union,...

Mantle Structure and Processes in Transition Zone of the Baikal Rift Zone
AbstractThe velocity structure of the mantle under the Baikal Rift Zone (BRZ) is investigated with the P‑wave receiver functions (PRFs) for a group...

Hadean mantle oxidation inferred from melting of peridotite under lower-mantle conditions
The early Earth’s mantle is believed to have been highly reducing when it formed from a magma ocean equilibrating with the core. Conversely, some...

The Structure of the Earth’s Crust and Lithospheric Mantle in the Central Part of the Lower Amur Metallogenic Zone and the Gold Distribution within It
In this study, we consider the deep structure of the Earth’s crust and the lithospheric mantle in the central part of the Lower Amur metallogenic...

Structure of the crust and lithospheric mantle beneath the central main Ethiopian rift
We use the complete Bouguer anomaly (CBA) derived from GGMplus 2013 to model the lithosphere–asthenosphere boundary (LAB) depth, LAB temperature,...

Small-Scale Mantle Plumes: Imaging and Geodynamic Aspects
Columnar, upwelling masses of hot rock in the Earth’s mantle, called mantle plumes, are spectacular features of our planet because they supply the...

Deep Crustal and Upper Mantle Structures in North Africa: A Review
This chapter provides insight and understanding into the upper mantle and lower crust of North Africa. Much study, throughout the last few decades,...

Lithological structure of western Pacific lithosphere reconstructed from mantle xenoliths in a petit-spot volcano
The lithospheric mantle, formed at the mid-ocean ridge as a residue of crustal production, comprises theoretically depleted peridotite, but more...

Ultralow velocity zone and deep mantle flow beneath the Himalayas linked to subducted slab
The origins of ultralow velocity zones, small-scale structures with extremely low seismic velocities found near the core–mantle boundary, remain...

Depth of the lithospheric mantle discontinuities beneath the northwest flank of Oku Volcanic Complex, Cameroon Volcanic Line: constraints from mantle xenolith and teleseismic data
In Northwestern Cameroon, the northwest flank of Oku Volcanic Complex forms part of the continental sector of the Cameroon Volcanic Line (CVL)....

Structure, Materials and Processes in the Earth’s Core and Mantle
AbstractThis paper reviews current knowledge about the Earth’s core and the overlying deep mantle in terms of structure, chemical and mineralogical...

Hyperextended crustal structure of the Qiongdongnan Basin and subsequent magmatic influence from the Hainan mantle plume
The Qiongdongnan Basin (QDNB) is a rift basin located in the extension direction of the oceanic ridge of the Northwest Subbasin of the South China...

Retention of water in subducted slabs under core–mantle boundary conditions
The hydrated SiO 2 phase is a main carrier of water in subducting slabs in the lower mantle. Assuming its dehydration at high temperatures above the...

Progress in the numerical modeling of mantle plumes
The mantle plume model, as an integral part of the Earth’s internal convection system, is complementary to the theory of plate tectonics. They...
