Subduction, where one plate dives beneath another, controls long­-term whole-­Earth cycling of rocks, fluids, and energy. Plates subduct faster than they heat up, making them the coldest parts of the Earth’s interior. Fluids released from these cold plates rise into hotter overlying rocks, forming magma that feeds surface volcanism. Cold deep conditions associated with subduction complemented by hot shallow conditions under volcanic arcs are reflected in the presence of pairs of metamorphic belts, representing sites of ancient subduction.

Extraterrestrial organic matter is found in various extraterrestrial environments and in various forms. It forms in a variety of locations through different mechanisms in space. As such, its nature, distribution, formation mechanisms and locations are of particular interest. Some organic molecules are even considered as key players for the emergence of life on Earth and possibly beyond. Therefore, their detection and characterization can contribute to the understanding of the early solar system evolution as well as the origin of life. Despite decades of work and research, there are still many ..read more

Earth’s history is punctuated by volcanic episodes at a scale never witnessed by humans, known as large igneous provinces (LIPs). These extraordinary volcanic and tectonic events are associated with profound changes to planet Earth, including its climate and habitability. One of the major factors controlling the impacts of LIPs is the cocktail of gases emitted to the atmosphere and oceans. In this issue of Elements, we explore the versatile impacts of LIPs, from their connections to mass extinctions in aquatic and terrestrial environments to climate warming and global icehouse events.
