Application of 3D Raman Mapping on Complex Inclusions: A Case Study of the Styrian Basin Mantle Xenoliths (W‐Carpathian Pannonian Region)

open access: yesJournal of Raman Spectroscopy, EarlyView.
Recent advancements in spectral and spatial resolutions for Raman spectroscopy allow the analysis of fluid and melt inclusions. To explore the applicability of 3D Raman mapping, we conducted 3D Raman mapping on inclusions hosted by orthopyroxene in modally metasomatized mantle xenoliths from the Styrian Basin (W‐Carpathian Pannonian Region).

Co-estimation of core and lithospheric magnetic fields by a maximum entropy method [PDF]

open access: yesGeophysical Journal International, Volume 236, Issue 3, March 2024, Pages 1646-1667
Satellite observations of the geomagnetic field contain signals generated in Earth's interior by electrical currents in the core and by magnetized rocks in the lithosphere. At short wavelengths the lithospheric signal dominates, obscuring the signal from the core.

On the impact of the geospace environment on solar-lithosphere coupling and earthquake occurrence [PDF]

open access: yesarXiv, 2021
We have found that about two months after creating a new radiation belt in the inner magnetosphere due to a geomagnetic storm, an increasing seismic activity may occur near the magnetic field lines' footprint of a newly created radiation belt. The Combined Release and Radiation Effects Satellite (CRRES) detected a new radiation belt after a geomagnetic

Age-dependent seismic thickness and mechanical strength of the Australian lithosphere [PDF]

open access: yes, 2002
We present constraints on the regional variations of the seismic and mechanical thickness of the Australian lithosphere. We infer the seismic thickness from a waveform tomographic model of S-wave speed, and as a proxy for the elastic thickness we use the

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

open access: yes, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

Subparallel thrust and normal faulting in Albania and the roles of gravitational potential energy and rheology contrasts in mountain belts [PDF]

open access: yes, 2009
The active tectonics of Albania and surrounding regions, on the eastern margin of the Adriatic Sea, is characterized by subparallel thrust and normal faulting which, we suggest, is likely to be related to gravitational potential energy contrasts between ...

Vineyard maturity increases arbuscular mycorrhizal and decreases plant pathogen fungal relative abundance in bulk soil across a 1,000 km Chilean gradient

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wine production has a significant impact on the global economy. Despite this, the microbial composition of the terroir has not been studied sufficiently, particularly in the southern hemisphere. Here, we investigated how bulk soil fungal communities are affected by several abiotic and biotic factors across 1,000 km of Chilean vineyards.

Seismic anisotropy across Adria plate, from the Apennines to the Dinarides

open access: yesFrontiers in Earth Science, 2022
The Adria microplate has the particular feature to be involved in two subduction systems with slab dipping in opposite directions, one toward west beneath the Apennines and the other to the east beneath the Dinarides.
