Some new insights into the geochronology of the Western Karelia Subprovince, Finnish Lapland [PDF]

Bulletin of the Geological Society of Finland, 2020
Archean terranes are generally poorly exposed and structurally complicated, making models of geological evolution difficult to establish. Because of pervasive metamorphism, strong deformation, and poorly exposed bedrock, the stratigraphy, geochronology ...

Direct Calibration Method for LA-HR-ICP-MS Apatite U-Pb Dating

Yankuang ceshi, 2022
BACKGROUND Apatite is a common U-bearing accessory mineral with a U-Pb closure temperature of ~500℃, making U-Pb dating of apatite a potentially valuable thermochronometer.

Technical note: LA–ICP-MS U–Pb dating of unetched and etched apatites [PDF]

Geochronology, 2021
The same unetched and chemically etched apatite crystals from five rock samples were dated by the U–Pb method via laser ablation inductively coupled plasma mass spectrometry (LA–ICP-MS).

Dinamika nakupljanja olova u listu i dijelovima ploda bajama

Poljoprivreda, 2023
Plodovi bajama (jezgra) smatraju se diljem svijeta zdravom hranom jer osim svoje visoke nutritivne vrijednosti u povećanim koncentracijama sadrže i esencijalne bio-molekule, koje pozitivno djeluju na ljudski metabolizam i istodobno preveniraju najvažnije

Establishing Provenance from Highly Impoverished Heavy Mineral Suites: Detrital Apatite and Zircon Geochronology of Central North Sea Triassic Sandstones

Geosciences, 2022
A study of Triassic sandstones in the central North Sea, UK, has shown that combined detrital zircon and apatite geochronology and apatite trace element analysis is a powerful tool for reconstructing provenance for sandstones with diagenetically ...

U-Pb memory behavior in Chicxulub's peak ring — Applying U-Pb depth profiling to shocked zircon [PDF]

Chemical Geology, 2019
The zircon U-Pb system is one of the most robust geochronometers, but during an impact event individual crystals can be affected differently by the passage of the shock wave and impact generated heat. Unraveling the potentially complex thermal history recorded by zircon crystals that experienced variable levels of shock and heating, as well as ...

Towards in situ U–Pb dating of dolomite [PDF]

Geochronology, 2020
Abstract. Recent U–Pb dating by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has demonstrated that reasonable precision (3 %–10 %, 2σ) can be achieved for high-resolution dating of texturally distinct calcite phases. Absolute dating of dolomite, for which biostratigraphy and traditional dating techniques are very limited ...

U-Pb geochronology of the Fort Augustus granite gneiss: constraints on the timing of Neoproterozoic and Palaeozoic tectonothermal events in the NW Highlands of Scotland [PDF]

, 2001
The West Highland granite gneiss suite in Inverness-shire, Scotland, represents a series of S-type, anatectic granites formed by partial melting of host Neoproterozoic metasediments of the Moine Supergroup.
