Fennoscandia is the key area for glacial isostatic adjustment (GIA) research. Owing to its
long settlement and excellent infrastructure, ongoing land uplift in the north as well as …

The longevity of deep continental roots depends critically on the rheological properties of
upper mantle minerals under deep upper mantle conditions. Geodynamic studies suggest …

Abstract In 1967 the Kibish Formation in southern Ethiopia yielded hominid cranial remains
identified as early anatomically modern humans, assigned to Homo sapiens,,,. However, the …

The mineral olivine dominates the composition of the Earth's upper mantle and hence
controls its mechanical behaviour and seismic anisotropy. Experiments at high temperature …

Synthetic forsterite samples were shear-deformed at 11 GPa, 1400° C in the multianvil
apparatus. The deformation microstructures have been characterised by SEM, EBSD, X-ray …

We report global shear‐wave velocity structure and radial anisotropy in the upper mantle
obtained using finite‐frequency surface‐wave tomography, based upon complete three …

The effects of pressure on crystallographic preferred orientation (CPO) of olivine aggregates
were investigated through simple-shear deformation experiments at pressures between 2.1 …

San-Carlos olivine rheology was investigated at pressure (P) up to 9GPa and temperature
(T) lower than 890° C. Six powder specimens were cold compressed and sintered into …

Shear deformation experiments on dry hot-pressed polycrystalline San Carlos olivine have
been conducted at 4.9–9.6 GPa, 1300–1870K and strain rates of 0.6–7.4× 10− 5s− 1 using a …

Knowledge of the rheological properties of mantle materials is critical in modeling the
dynamics of the Earth. The hightemperature flow law of olivine defined at mantle conditions …
