Structural geology is the study of the deformation of the surface and subsurface of the Earth and other planetary bodies. This deformation reflects past changes in local and regional stress and strain, and can be used to reconstruct past crustal movements and dynamics.
A 3D stochastic declustering algorithm, applied to data from the dense seismic array at the Alto Tiberina Fault system, Italy, suggests the difference between earthquake size distributions of independent and triggered seismicity is not an artifact.
The Cenozoic eastward growth of the Tibetan Plateau can be explained by slab tear and the resulting mantle flow beneath the eastern region, according to analysis of seismic tomography, tectonic and magmatic records of the Indian mantle lithosphere.
Magmatism in the Guyana/Suriname Margin evolved from a magma-rich hotspot, through normal oceanic crust, to magma poor extension and magma starved mantle exhumation, due to changes in magma budget over time, as revealed by seismic and geophysical data from the Demerara Plateau.
Nephrite jade is a semi-precious gemstone composed of tiny crystals and needles of amphibole. Here, Matthew Tarling and Steven Smith describe how its origins lead to inner toughness and beauty.
While it may feel cold to the touch, Sheng Fan and David Prior explain that ice on Earth is relatively hot. Understanding ‘hot’ ice physics during deformation is critical in determining future sea-level rise.
An article in Geochemistry, Geophysics, Geosystems established a soil gas monitoring approach to identify hydrogen-fertile regions in the Pyrenean foothills.
Near-surface stress patterns, influenced by topography, control the size and location of the largest landslides — but not necessarily smaller ones — according to a study of mountains at the eastern edge of the Tibetan Plateau.
