Unravelling the timing and rate of subduction-zone metamorphism and H2O release requires linking time to the compositional changes of petrogenetic indicator minerals in blueschists and eclogites. Garnet is a key mineral in this regard, as it …

Long-term, high resolution measurements of dual clumped isotopes in carbonates
using the Perspective IS
Long-term, high resolution measurements of dual clumped isotopes in carbonatesusing the Perspective IS The Nu Perspective IS stable isotope ratio mass spectrometer is designed to measure isotopic clumping in gas …
Nanoscale isotopic evidence resolves origins of giant Carlin-type ore deposits
ABSTRACT The western North American Great Basin’s Carlin-type deposits represent the largest accumulation of gold in the Northern Hemisphere. The controversy over their origins echoes the debate between Neptunists and …

Using multiple shots per pixel and a composite image technique to extend dynamic range of imaging with the Vitesse
Abstract Bár általánosan elismert, hogy az La-ICP-MS a leggyorsabb technika elemtérképek készítésére. A köztudományú vélekedés szerint ebben az esetben romlik a kimutatási határ a kép készítése során. A modern lézeres ablációs …
Potassium isotope evidence for sediment recycling into the orogenic lithospheric mantle
Abstract Post-collisional highly potassic magmatism in large orogenic belts has been taken as evidence for recycling of continent-derived K-rich sediments within the orogenic lithospheric mantle. Potassium isotopes may provide important …

Tracing Fe sources in the suspended particulate matter (SPM) in the Mun River: application of Fe stable isotopes based on a binary mixing model
Abstract The Fe isotopic composition of the riverine suspended particulate matter (SPM) in the Mun River was found to improve the knowledge of the Fe isotope behaviors in the surface …
Review of techniques, challenges, and new developments for calcium isotope ratio measurements
Abstract Calcium isotope meaurements apply to problems spanning the ‘cosmos to benthos.’ Fractionation, source mixing, radioactive decay, and nucleosynthetic processes cause variations in Ca isotope ratios, which can be measured …
Potassium isotopic composition of various samples using a dual-path collision cell-capable multiple-collector inductively coupled plasma mass spectrometer, Nu instruments Sapphire
Abstract Mass-dependent K isotopic fractionations can be used to trace cosmochemical, geological, and biological processes such as evaporation/condensation, core formation, magmatic processes, weathering, and cellular metabolism. However, the application of …
Needles in haystacks: using fast-response LA chambers and ICP-TOF-MS to identify asbestos fibres in malignant mesothelioma models
Abstract Malignant mesothelioma is an aggressive cancer associated with exposure to asbestos. Diagnosis of mesothelioma and other related lung diseases remains elusive due to difficulties surrounding identification and quantification of …
Single- and Multi-Element Quantification and Characterization of TiO2 Nanoparticles Released From Outdoor Stains and Paints
Abstract With growing applications of TiO2 nanoparticles (NPs) in outdoor surface coatings, notably in paints and stains, their release into the environment is inevitable. While NP release has potential ecotoxicological …
