Melt migration and melt-rock reaction in the Alpine-Apennine peridotites: Insights on mantle dynamics in extending lithosphere [PDF]

open access: yes, 2018
The compositional variability of the lithospheric mantle at extensional settings is largely caused by thereactive percolation of uprising melts in the thermal boundary layer and in lithospheric environments.The Alpine-Apennine (A-A) ophiolites are ...

Fault (Re)Activation and Fluid‐Induced Seismicity: An Example From the Val d’Agri Intermontane Basin (Southern Italy)

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 7, July 2024.
Abstract Fluid‐induced seismicity has been a particularly emphasized mechanism over the last few years, especially after fluid‐related, moderate‐to‐large earthquakes have been observed in several locations around the globe. Several studies suggest that the relationships between seismicity and fluid presence are related to variations in the stress state

Plagioclase Peridotites in Ocean-Continent Transitions: Refertilized Mantle Domains Generated by Melt Stagnation in the Shallow Mantle Lithosphere [PDF]

open access: yes, 2017
The existence of different mantle domains exposed in ocean-continent transition zones provides a framework for understanding the generation of ultramafic seafloor along magma-poor rifted margins.

Pyroxenite xenoliths from Marsabit (Northern Kenya): evidence for different magmatic events in the lithospheric mantle and interaction between peridotite and pyroxenite [PDF]

open access: yes, 2018
Garnet-bearing and garnet-free pyroxenite xenoliths from Quaternary basanites of Marsabit, northern Kenya, were analysed for microstructures and mineral compositions (major and trace elements) to constrain the thermal and compositional evolution of the ...

Estimation of recharge in mountain hard-rock aquifers based on discrete spring discharge monitoring during base-flow recession [PDF]

open access: yes, 2021
Estimation of aquifer recharge is key to effective groundwater management and protection. In mountain hard-rock aquifers, the average annual discharge of a spring generally reflects the vertical aquifer recharge over the spring catchment.

Petrology, Mineral and Isotope Geochemistry of the External Liguride Peridotites (Northern Apennines, Italy) [PDF]

open access: yes, 2017
Mantle peridotites of the External Liguride (EL) units (Northern Apennines) represent slices of subcontinental lithospheric mantle emplaced at the surface during early stages of rifting of the Jurassic Ligurian Piemontese basin.

Shallow landslide initiation on terraced slopes. Inferences from a physically based approach [PDF]

open access: yes, 2018
In the last years, great efforts have been made to improve the assessment of the temporal and spatial occurrence of rainfall-induced shallow landslides.

Timescales of Oceanic Lithosphere Hydration: Constraints from Rodingites, Apennines, Italy [PDF]

open access: yes, 2023
Thesis advisor: Ethan BaxterSerpentinites assume a critical role in geochemical and geophysical cycles, from recycling fluid into the sub-arc mantle to facilitating exhumation within subduction zones.

GEOLOGIC OUTLINE OF THE TUSCANY-LATIUM CONTINENTAL SHELF (NORTH TYRRHENIAN SEA): SOME GEODYNAMIC IMPLICATIONS [PDF]

open access: yes, 2017
An old high-penetration seismic survey of the Tuscany-Latium continental shelf furnished use­ful information on Neogene stratigraphy, structural setting and paleogeography. The seismically penetrated stratigraphic column is composed of five seismic units

Crustal-scale magmatic systems during intracontinental strike-slip tectonics: U, Pb and Hf isotopic constraints from Permian magmatic rocks of the Southern Alps [PDF]

open access: yes, 2018
The Southern Alps host volcano-sedimentary basins that formed during post-Variscan extension and strike-slip in the Early Permian. We present U-Pb ages and initial Hf isotopic compositions of magmatic zircons from silicic tuffs and pyroclastic flows ...
