Technical note: RA138 calcite U–Pb LA-ICP-MS primary reference material Open
A promising primary reference material for U–Pb laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) carbonate dating is analysed and reported here. The new reference material (RM) is a botryoidal cement (C1) from sample…
Reconstructing the Evolution of Foreland Fold‐And‐Thrust Belts Using U‐Pb Calcite Dating: An Integrated Case‐Study From the Easternmost Jura Mountains (Switzerland) Open
This case‐study from the Jura Mountains in the foreland of the European Alps demonstrates how the coupling of subsurface analysis and U‐Pb carbonate dating can provide absolute timing constraints and shortening rate estimates of fold‐and‐t…
Comment on gchron-2024-7 Open
Abstract. A promising primary reference material for U-Pb LA-ICP-MS carbonate dating is analysed and reported here. The new RM is a botryoidal cement (C1) from sample RA138. The sample was collected in outcrop strata of mid-Carboniferous (…
Understanding the origin of dolomite in the sedimentary record: the contribution of clumped isotope thermometry. Open
The formation of dolomite in the sediments of the Sabkha of Abu Dhabi was the subject of Judy’s PhD thesis and the question of the origin of dolomite remained at the center of her scientific interests throughout her career. The main focus …
Clumped isotopes in carbonates: state of the art and open questions  Open
Since its establishment almost 20 years ago, carbonate clumped isotope thermometry (Δ47, Δ48) has grown to the most widely applied branch of the rapidly evolving field of clumped isotope geochemistry. An increasing number of laboratories w…

A promising primary reference material for U-Pb LA-ICP-MS carbonate dating is analysed and reported here. The new RM is a botryoidal cement (C1) from sample RA138. The sample was collected in outcrop strata of mid-Carboniferous (Uppermost …
Structural architecture and maturity of Val d’Agri faults, Italy: Inferences from natural and induced seismicity Open
The Val d’Agri Basin is a Quaternary sedimentary basin topping multiple tectonic units of the southern Apen \nnines fold-and-thrust belt and a giant oilfield within deeper Apulian Platform carbonates. This basin is bounded \nby the seismic…
New Experimental Constraints on Clumped Isotope Bond Reordering in Dolomite Open
The conditions controlling the formation of sedimentary dolomite are still poorly understood despite decades of research. Reconstructing formation temperatures and δ18O of fluids from which dolomite has precipitated is fundamental to const…
Clumped isotope bond reordering in dolomite: new experimental constraints based on low temperature sedimentary dolomites Open
Carbonate clumped isotope thermometry can be used to constrain the formation temperature and the oxygen isotope composition of the fluids involved in the precipitation of carbonate minerals. It exploits the preference of 13C-18O bonds in c…
Fingerprinting Kinetic Isotope Effects and Diagenetic Exchange Reactions Using Fluid Inclusion and Dual‐Clumped Isotope Analysis Open
Geochemical analyses of carbonate minerals yield multiple parameters which can be used to estimate the temperature and water composition at which they formed. Analysis of fluid trapped in minerals is a potentially powerful tool to reconstr…
Using Precambrian carbonates for seawater isotope reconstructions: constraints from LA-ICP-MS U-Pb geochronology of a post-Sturtian cap dolomite, Brazil Open
Global seawater isotope reconstructions from Precambrian marine carbonates must overcome particular difficulties on two fronts: i) accurate age constraints for global stratigraphic correlations and interpretations, and ii) the relative tim…
U–Pb dating of middle Eocene–Pliocene multiple tectonic pulses in the Alpine foreland Open
Foreland fold-and-thrust belts (FTBs) record long-lived tectono-sedimentary activity, from passive margin sedimentation, flexuring, and further evolution into wedge accretion ahead of an advancing orogen. Therefore, dating fault activity i…

Absolute Age and Temperature Constraints on Deformation Along the Basal Décollement of the Jura Fold‐and‐Thrust Belt From Carbonate U‐Pb Dating and Clumped Isotopes Open
During its late‐stage evolution, the European Alpine orogen witnessed a northwest‐directed propagation of its deformation front along an evaporitic basal décollement into the foreland. This resulted in the decoupling of the northern Alpine…
U-Pb dating of middle Eocene-middle Pleistocene multiple tectonic pulses in theAlpine foreland Open
Foreland fold-and-thrust belts record long-lived tectonic-sedimentary activity, from passive margin sedimentation, flexuring, and further involvement into wedge accretion ahead of an advancing orogen. Therefore, dating fault activity is fu…

Evaluating the reliability of U–Pb laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) carbonate geochronology: matrix issues and a potential calcite validation reference material Open
We document that the reliability of carbonate U–Pb dating by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is improved by matching the aspect ratio of the LA single-hole drilling craters and propagating long-term …
