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

Asthenosphere flow and plate motions [PDF]
Summary. A dynamical theory of flow in the asthenosphere is developed by treating it as a thin layer of Newtonian viscous fluid, pushed horizontally by the dense sinking slabs attached to some plates and by the differences in heating under continental and oceanic crust.

The relationship between upper mantle anisotropic structures beneath California, transpression, and absolute plate motions [PDF]
We calculated SKS splitting parameters for the California Integrated Seismic Network. In southern California, we also estimated splitting in the upper 100 km using azimuthal anisotropy determined from surface waves.

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

Computation of a combined spherical-elastic and viscous-half-space earth model for ice sheet simulation [PDF]
This report starts by describing the continuum model used by Lingle & Clark (1985) to approximate the deformation of the earth under changing ice sheet and ocean loads.

Recovery of an oxidized majorite inclusion from Earth’s deep asthenosphere
Novel discovered majorite from a depth of at least 380 km provides unique window into the redox state and dynamics of the mantle. Minerals recovered from the deep mantle provide a rare glimpse into deep Earth processes.

Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.
