Trace Element Content and U-Pb Geochronology of Detrital Rutile in the Cretaceous-to-Eocene Julian and Brkini Flysch Basins (SE Alps and NW Dinarides, Italy and Slovenia)

Matteo Velicogna, Martina Greco, Lorenzo Tavazzani, Chiara Pisoni et autres

The Cretaceous-to-Eocene Julian (JB) and Brkini (BK) flysch basins have recently been studied for their heavy mineral assemblages; however, the rutile component has so far been neglected. To fill this gap, this study explores their detrital rutile trace element contents and U-Pb …

Raman non-destructive analysis of visible tephra layers in ice cores

Marco Rabassi, Sergio Andò, Barbara Delmonte, Claudio Artoni et autres

Ice cores are exceptional archives of past climate variability, preserving forcing factors and proxies of the climate system’s response. Volcanic eruptions, when recorded as englacial tephra layers, provide insights into explosive volcanism, volcano–climate interactions, and enable long-range synchronization of paleoclimate records, provided …

Size-resolved mineralogy and grain size-shape analysis of airborne and deposited mineral dust in northern China

Katja Bohm, Hui Tang, Bin Wang, Sergio Andò et autres

The chemical and physical properties of atmospheric mineral dust play a key role in determining its climatic and environmental effects. These properties also vary globally, highlighting the importance of observational studies and regional investigations in enhancing global models. One of the major …

Characterisation and Correlation of Visible Tephra Horizons in the Beyond EPICA Oldest Ice Core

Carys Thomas, Siwan Davies, Barbara Delmonte, Marco Rabassi et autres

Antarctic ice cores provide exceptional archives of past climates and volcanic activity. Advances in sampling and analytical techniques are now enabling the detection and characterisation of both visible and cryptotephra deposits across increasingly long climate records. The Beyond EPICA Oldest Ice (BE-OI) …

High-resolution heavy mineral analysis of marine sediments in the Ross Sea, Antarctica

Sergio Andò, Marco Rabassi, Marta Barbarano, Guido Pastore et autres

In Antarctica, ocean currents and ice sheet dynamics affect sediments, their erosion, transport and deposition, and the sedimentological record represents a precious natural archive of the past climate. The study of the mineralogical composition of modern sediments can be conducted by applying …

Persistence of pyrite in mountain river sediments sourced by landsliding in southeastern Taiwan

Enmanuel Cruz Muñoz, Sergio Andò, Eduardo Garzanti, Aaron Bufe et autres

Although pyrite (FeS₂) is highly reactive in oxygen-rich environments and is expected to be largely consumed through the weathering zone, observations from Taiwan indicate that pyrite grains can survive and be transported by fluvial systems. This rapidly uplifting island exhibits exceptionally high …

Deconvolving the Effects of Fluvial Transit and Storage on Preservation of Sedimentary Source Signals Using Heavy Minerals and Terrestrial Biomarkers

Sophia Dosch, Niels Hovius, Sergio Andò, Eduardo Garzanti et autres

Analysis of naturally occurring markers of environmental signals, or proxy analysis, in sedimentary records can yield valuable insights into the geologic past. However, these proxies may be altered between sediment source and sink by selective gain, loss, or transformation of individual organic …

Marine microplastics in the Baltic Sea under stormy conditions: the case of Dudley, Eunice and Franklin storms in February 2022

Ilaria Guardamagna, Piotr Markuszewski, Mikołaj Mazurkiewicz, Przemysław Makuch et autres

This study investigates the distribution, characteristics, and composition of marine microplastics (MPs) in the Baltic Sea during winter, under the meteorological conditions associated with the Dudley, Eunice, and Franklin storms of 2022. Sampling was conducted aboard r/v Oceania in February 2022 at …

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

Sergio Andò, Giovanni Vezzoli, Marta Barbarano, Laura Fornasini et autres

ABSTRACT A new protocol for the laboratory preparation of archaeological samples, aimed at concentrating and analysing heavy minerals by optical microscope and Raman spectroscopy, is presented. The potential of heavy‐mineral studies in geoarchaeology could be enhanced conspicuously by using a state‐of‐the‐art protocol …

Combining instrumental, historical, and coastal marine sedimentary archives to analyse floods variability in northwestern Italy during the last thousand years

Giovanni Coletti, Laura Borromeo, Luca Fallati, Marco Luppichini et autres

Understanding Earth's changing climate is a crucial challenge. However, the available time series of direct measurements are often insufficient to fully capture climatic processes that unfold over centuries and millennia. Combining history and geology can fill this gap. Focusing on rainfall and …
