Explores the behavior of carbon in minerals, melts, and fluids under extreme conditions
Carbon trapped in diamonds and carbonate-bearing rocks in subduction zones are examples of the continuing exchange of substantial carbon ...

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.

Geochemistry, Geophysics, Geosystems, 2020 The oceanic lithosphere is a primary component of the plate tectonic system, yet its evolution and its asthenospheric interaction have rarely been quantified by in situ imaging at slow spreading systems.

Geochemistry, Geophysics, Geosystems, 2021 The evolution of ocean lithosphere and asthenosphere are fundamental to plate tectonics, yet high resolution imaging is rare. We present shear wave velocity and azimuthal anisotropy models for the upper mantle from Rayleigh wave group velocities from ...

Stepwise Lithospheric Delamination Leads to Pulsed Cenozoic Uplifts of Central Tien Shan
Lithosphere, 2022 The Tien Shan provides an ideal site to study mechanism of intracontinental orogeny due to distant effect of Indo-Asian collision. We investigate lithospheric structures, in particular the lithosphere-asthenosphere boundary (LAB), of Central Tien Shan ...

Геодинамика и тектонофизика, 2015 It is revealed that high-Mg lavas (MgO=11.0–15.8 wt. %) are spatially controlled by linear zones extending for more than 90 km and demonstrate chemically distinct differences from moderately-Mg compositions (MgO=3.0–11.0 wt.

Melting of recycled ancient crust responsible for the Gutenberg discontinuity
Nature Communications, 2020 The seismic Gutenberg discontinuity has long been associated with the lithosphere-asthenosphere boundary, yet the physical explanation of what is causing the discontinuity remains debated.

Geochemistry, Geophysics, Geosystems, 2018 Juxtaposed terranes of highly varied tectonic history make up the contiguous U.S.: the tectonically active western U.S., the largely quiescent Archean and Proterozoic cratons of the central U.S., and the Phanerozoic orogen and rifted margin of the ...

Geodesy and Geodynamics, 2019 The average density of 3300 kg m−3 is often attributed for the asthenosphere. In this study, we inspect this value by estimating the average value of the (upper) asthenosphere based on applying the gravimetric forward modelling of major known ...

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
