Abstract Measuring the carbon stable isotope ratio (13C/12C, expressed as δ13CCO2) in geogenic CO2 fluids is a crucial geochemical tool for studying Earth's degassing. Carbon stable isotope analysis is traditionally performed by bulk mass spectromet

Granulites and associated dykes from the less well-studied southern Ivrea–Verbano Zone (around Ivrea town) are characterized by combining field, macro, micro and chemical (major and trace-element mineral composition) data to identify chemical and r

A deep, magnitude 4.6 earthquake, beneath Milan, Italy, in December 2020 involved a major explosive component that may indicate outgassing of carbon dioxide from ascending carbonate-rich melts, according to moment tensor inversion of the seismic sour

Outgassing of CO2 during collisional orogeny can be explained by the generation of immiscible CO2-rich fluids and hydrosaline brines in metamorphosed sediments, according to thermodynamic modelling applied to the Himalaya.

Antigorite dehydration is a process able to release, in comparison with other minerals, the highest amount of H2O from a subducting slab. The released fluid delivers critical elements (e.g., S, Cu, and REE) to the overlying subarc mantle, modifying t

Diamonds can give us clues to the processes regulating deep carbon transport within the Earth. Here, the author discovers evidence from diamond coatings that organic compounds exist at great depth in Earth’s interior, and furthermore, that organic

In the Italian Alps, the Ivrea-Verbano Zone (IVZ) is known as one of the best preserved, i.e., not re-equilibrated during Alpine metamorphism, Variscan Units and, from SW to NE, it extends from Ivrea to Locarno. The sub-units constituting the IVZ are

Raman spectroscopy is gaining ground in the analysis of microplastics, especially due to its high spatial resolution that allows the investigation of small plastic particles, whose numeric abundance is argued to be particularly relevant in aquatic sy

Fluids are essential to the physical and chemical processes in subduction zones. Two types of subduction-zone fluids can be distinguished. First, shallow fluids, which are relatively dilute and water rich and that have properties that vary between su

The Pico do Fogo volcano, in the Cape Verde Archipelago off the western coasts of Africa, has been the most active volcano in the Macaronesia region in the Central Atlantic, with at least 27 eruptions during the last 500 years. Between eruptions fuma
