Dimitri Laurent explores a typical gallery in the Nébélé Cave, which was formed by sulfuric acid speleogenesis. You can see a deep notch that indicates the former presence of a river, and sodium sulfate on the left that is produced from weathering by sulfuric acid. Credit: Christophe Durlet

Fossils Reveal Dinosaurs of Prehistoric Patagonia

Boudinage in brecciated dolostone rocks of the Panamint Range (Wildrose Area, Death Valley National Park). New research shows that periclase is stronger than bridgmanite in earth's lower mantle, analogous to boudins developing in rigid ("stronger") rocks among less competent ("weaker") rocks.

New results reveal surprising behavior of minerals deep in the Earth

A. The lithospheric breakup-collision coupling system, in which collisional thickening of the continental crust is coupled with lithospheric breakup due to asthenospheric upwelling for active rifting. B. The seafloor spreading-lithospheric subduction coupling system, in which the oceanic slab is subducted to depths of >80–100 km for the gravitational pull, providing far-field stresses for passive rifting.

Plate tectonics in the twenty-first century

‘Superdeep’ diamond deepens our understanding of plate tectonics

The Northwestern research team of seismologists and statisticians has developed an earthquake probability model that is more comprehensive and realistic than what is currently available.

New study reveals, how foreshock waves interact with Earth’s magnetosphere. Foreshock waves are able to tune the shock, making it alternatively stronger or weaker. These waves could only be detected in a narrow region behind the shock. (Image: Lucile Turc)

New study models the transmission of foreshock waves towards Earth

Deep learning can predict tsunami impacts in less than a second

Summer precipitation and black carbon emission characteristics. a The spatial pattern of summer precipitation using the Climatic Research Unit (CRU) dataset overlain with summer 500 hPa wind fields for the period 2001–2016, using the ERA-Interim dataset over the Tibetan plateau (TP) and South Asia (denoted by red polygon). NTP and STP delineate the northern and southern Tibetan plateau boundaries.
