RioM‐1: A New Calcite Reference Material for U‐Pb LA‐ICP‐MS Geochronology

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 1, Page 181-199, March 2026.
Key Points RioM‐1 calcite was characterised for trace elements, U‐Pb geochronology, Sr and O isotopes using ID‐TIMS, LA‐ICP‐MS and SIMS. U‐Pb dates from ID‐TIMS and LA‐ICP‐MS across several independent laboratories returned identical results within uncertainty.

DATAMESOP: DATAset on Stable Isotope Measurement (Strontium, Oxygen and Carbon) of Archaeological and Non-Archaeological Materials from South-West Asia for MESOPotamia

open access: yesJournal of Open Archaeology Data
DATAMESOP is one of the first comprehensive isotopic datasets aimed at supporting bioarchaeological studies in ancient Mesopotamia. The dataset compiles radiogenic strontium and stable carbon, and oxygen isotope measurements from both archaeological ...

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 389-404, March 2026.
Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to

Seismic and isotopic evidence for depth-dependent mantle sources of intraplate basalts from Eastern China

open access: yesCommunications Earth & Environment
The origin of intraplate basalts remains controversial, despite numerous isotope and seismic studies. Here we employ thermodynamic modeling with MAGEMin to integrate the Sr-Nd-Hf isotopes of basaltic volcanics with the seismic velocities of their mantle ...

Characterization of Modern and Fossil Mineral Dust Transported to High Altitude in the Western Alps: Saharan Sources and Transport Patterns

open access: yesAdvances in Meteorology, 2012
Mineral dust aerosols recently collected at the high-altitude Jungfraujoch research station (N, E; 3580 m a.s.l.) were compared to mineral dust deposited at the Colle Gnifetti glacier (N, E; 4455 m a.s.l.) over the last millennium.

Recent Development in Radiogenic Isotope Geology

open access: yesJournal of Geography (Chigaku Zasshi), 1964
Several topics of the research in radiogenic isotope geology are briefly reviewed. This short review consists of four parts; (i) recent development in the instrumentation, (ii) in the methodology, (iii) topics on the mantle-crustal evolution on the basis of Pb, Sr isotope growth and (iv) geochronology of ocean floors.

Lead isotope constraints on the mantle sources involved in the genesis of Mesozoic high-Ti tholeiite dykes (Urubici type) from the São Francisco Craton (Southern Espinhaço, Brazil)

open access: yesBrazilian Journal of Geology
: The first results of Pb isotope compositions of the high-Ti Mesozoic dykes of the Southern Espinhaço are presented. The results do not show large variations and are significantly more radiogenic than the Pb isotope compositions of the high-Ti ...

Multifaceted orogenic fluid dynamics unraveled by hydrothermal epidote [PDF]

open access: yesEuropean Journal of Mineralogy
Characterizing fluid circulation in orogens is key to understanding orogenic processes because fluid–rock interaction modifies the physical properties of rocks, hence their response to deformation and, for example, their suitability for radioactive waste
