Thermally metamorphosed CM chondritic clasts reveal deep interior conditions: Insights from thermometry

We studied four coarse-grained crystalline clasts within CM carbonaceous chondrites to constrain their thermal history and origin. These clasts have near-identical mineralogies, dominated by olivine (Fa 37 or Fa 40 ), with lesser quantities of high-Ca pyroxene (diopside: Fs 10-11...

Italian Fluvial Sediment Transport Database: a comprehensive hub for archiving and analyzing hydrological data

Fluvial sediment transport plays a key role in geomorphological and hydrological processes, influencing river morphology, watershed and coastal sediment balances, and the environmental response to climatic and anthropogenic changes. In Italy, the availability of homogeneous and l...

The Italian geothermal play-typing, a blueprint for unlocking national geothermal development

Abstract Italy has a long history of geothermal use, but a comprehensive, updated national assessment has been lacking. This study is the first to systematically evaluate geothermal systems across Italy using the modern geothermal play concept. The primary objective is to provide...

Technique Analysis of Filter-Clogging Particulate Matter in Eddy Covariance Systems in a Volcanic Environment

The eddy covariance (EC) technique is a key tool in environmental monitoring, enabling continuous and non-invasive measurement of carbon dioxide (CO2) fluxes at the ecosystem–atmosphere interface. In environments characterized by high levels of airborne particulates, such as volc...

Lower-crustal unzipping drives active orogenic deformation

The Apennines-Tyrrhenian Sea system allows us to investigate seismotectonics in coupled thrust belt and back-arc realms driven by subduction retreat, continental collision, and crustal delamination. Since the late Miocene, active extension has progressively migrated forelandward,...

Assessing the Climate and Habitability of Tidally Locked Rocky Exoplanets

Tidally locked exoplanets orbiting M dwarf stars are prime targets in the search for habitable worlds, yet their complex climate dynamics challenge conventional models of habitability. We homogeneously estimated the liquid–water habitability of exoplanets with the highest up-to-d...

Mantle heterogeneity drives spreading center dynamics at Arctic Mid-Ocean Ridge

The Mohns and Knipovich mid-ocean ridges in the Arctic Ocean are ideal settings to investigate the dynamics of spreading centers, being the region affected by intricate interplays between oblique plate kinematics and curved plate boundary geometry. Furthermore, significant mantle...

Does an Unconventional Source with a High Silica Content (Obsidian) or a High Alumina Content (Bauxite) Affect the Type of Potassium Zeolite Formation? Preliminary Data on Synthetic Products’ Efficiency in Ammonium Removal

In this paper, obsidian (OS) and bauxite (BX) are used to synthesize zeolites via KOH prefusion, followed by a conventional hydrothermal process (HY) or an unconventional vapor-phase crystallization method (VPC) at 90 °C. The results indicate that, due to their chemical and miner...

Early-mid Holocene Ross Sea extreme wave heights reflect sea ice retreat and ocean-atmosphere interactions

Abstract Antarctic coastal systems preserve valuable records of postglacial environmental change and extreme storm events. On Inexpressible Island, Ross Sea, we integrated geomorphic mapping, boulder measurements, exposure dating, radiocarbon constraints, and hydrodynamic analysi...
