Preparation and Identification of Heavy Minerals for Archaeometrical Studies: Villa of Fiumana (FC), Italy

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1302-1314, November 2025.
This paper presents a new protocol for the laboratory preparation of archaeological samples. Ceramics that have been hand‐crafted using different sediments as raw materials were collected in a Roman Villa sited in Fiumana (FC), Italy. This method aims at concentrating and analysing heavy minerals in the 15–250 μm grain size fraction, studying the ...

The Contribution of the Petrological Iterative Approach in Reconciling the UHP Natural Data Set With Geodynamic Models in the Continental Western Alps

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Pressure and temperature estimates of metamorphic terranes are increasingly retrieved from forward thermodynamic modeling coupled with isopleth thermobarometry. Although geodynamic reconstructions are mathematically derived, thermobarometric estimates are limited by a lack of quantitative constraints, especially on their uncertainties.

Ductile to Brittle Progression During Exhumation Controlled the Architecture of the Naukluft Nappe Complex, Namibia

Tectonics, Volume 44, Issue 8, August 2025.
Abstract Mountain belt architecture and evolution can be represented by frictional Coulomb wedges, a simplification that works well in the shallow deformation conditions of many foreland fold‐thrust belts. However, thin‐skinned fold‐thrust belts often occur in rocks that can deform ductily at low temperature.

Magnetic and Paleomagnetic Characterization of the Ivrea‐Verbano Lower Crust Body (NW Italy): Assessing the Magnetization of Variscan‐Age Lower Crust

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The source of high‐intensity magnetic anomalies from (mostly Precambrian) lower crust of continent interiors has long been debated, as it requires speculative rocks yielding 2–6 A/m magnetization. We report on the magnetic and paleomagnetic investigation of the Ivrea‐Verbano Zone (IVZ), Western Alps, where metamorphic and intrusive lower crust

Long-wave Marangoni instability with vibration [PDF]

, 2006
The effect of vertical vibration on the long-wave instability of a Marangoni system is studied. The vibration augments the stabilizing effect of surface tension in bounded systems.

Early Cretaceous to Miocene Tectonic Evolution of the NW Cyclades Based on 40Ar/39Ar Multiple Single Crystal Dating of White Mica From Andros

Tectonics, Volume 44, Issue 6, June 2025.
Abstract The Aegean region marks the convergent boundary between the African and Eurasian plates, reflecting complex tectonic processes, including the closure of the Pindos ocean. The Pelagonian unit (PU) forms the core of mainland Greece and was part of the Eurasian continental margin, while the Pindos oceanic crust subducted beneath it.

Recycling Subducted Organic Carbon as Diamonds: An Example From the New Caledonia Forearc Ophiolite

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Micro‐diamonds and moissanite (SiC) have been identified in ophiolitic mantle harzburgites and chromitites of the New Caledonian Peridotite Nappe. The pale yellow (100–250 μm) micro‐diamonds and light blue moissanite (mean −26.5‰, range −33.5‰ to −23.8‰ and mean −26.9‰, range −31.8‰ to −25.6‰ respectively) exhibit consistently strong negative ...

Morphodynamics of Cold High Latitude Semiarid Regions: The Example of Ellef Ringnes Island, Nunavut [PDF]

, 2005
In this paper we use the example of Ellef Ringnes Island, Nunavut, to examine active geomorphic processes in a high latitude semiarid region. The spectacular landscape of Ellef Ringnes Island is principally the result of fluvial erosion controlled by ...

Wellbore Stability Prediction Model for Complex Reservoirs: Application to the Bozi Gas Field in the Tarim Basin

Energy Science &Engineering, Volume 12, Issue 12, Page 5590-5601, December 2024.
ABSTRACT The primary objective of this paper is to propose a method for predicting the safe mud weight window within the Bozi gas field situated in the Tarim Basin and establish a 3D wellbore stability model. The approach combines Mogi–Coulomb criterion using intermediate stress for wellbore shear failure.
