Solid Earth sciences encompass the study of the crust, mantle and core of the Earth and other rocky planetary bodies. Earth sciences include petrology, mineralogy, seismology, core studies, mantle dynamics, tectonics, volcanology, metamorphism, sedimentology, geomagnetism, palaeomagnetism, hydrogeology, and geomorphology. Sedimentary rocks are also used to study palaeontology and palaeoclimate.
What stabilized and strengthened the oldest, most robust blocks of continental crust billions of years ago during the Archaean eon has long been a mystery. It seems that a surprise helping hand might have come from the air above.
The trace-element compositions of mantle-derived basalts suggest that the asthenosphere has two distinct melt layers, with unique chemical compositions and physical properties.
Jones et al., use a laboratory apparatus to perform rheological measurements on real gas-pyroclast mixtures to uncover the flow properties of pyroclastic density currents, a lethal volcanic hazard.
The caldera of Campi Flegrei volcano shows space-dependent rheological behaviour due to the interplay between overpressure sources and geological structures, according to 3D tomography of b-values and correlation with subsurface structures.
Short-term strong wind events play a crucial role in the evolution and movement of barchan dunes, according to analyses of high-frequency wind sampling data and high-resolution topographic information
The field remains an unsafe and isolating workplace for many. We present resources to empower and guide researchers towards safer, more inclusive, and more equitable fieldwork practice.
Hydrous minerals within the Earth affect volatile cycling and mantle geodynamics. Jun Tsuchiya explains how stable phases of these minerals are being uncovered at increasingly high pressures.
