Inter-session excess variance of U/Pb and Pb/Pb ratios in LA-ICP-MS zircon dating is the largest contributor to systematic errors, which turn limit accuracy age determinations. Quantifying long-term reference materials allows for estimation samples, but such compilations are not available literature. Here, we present results over 100 measurement sessions six years seven common calculate a chara...

Previously, a large platinum (Pt) anomaly was reported in the Greenland ice sheet at the Younger Dryas boundary (YDB) (12,800 Cal B.P.). In order to evaluate its geographic extent, fire-assay and inductively coupled plasma mass spectrometry (FA and ICP-MS) elemental analyses were performed on 11 widely separated archaeological bulk sedimentary sequences. We document discovery of a distinct Pt a...

BACKGROUND Safety assessment of nanoparticles (NPs) requires techniques that are suitable to quantify tissue and cellular uptake of NPs. The most commonly applied techniques for this purpose are based on inductively coupled plasma mass spectrometry (ICP-MS). Here we apply and compare three different ICP-MS methods to investigate the cellular uptake of TiO2 (diameter 7 or 20 nm, respectively) an...

An enamel fragment from the Border Cave 5 specimen was analysed with non-destructive ESR combined with laser ablation ICP-MS for uranium profiling. We obtained an age of 74+/-5 ka which fits exactly into the chronological framework that has been previously established for Border Cave by a variety of dating techniques. The result lays at rest the view that BC5 could be of Iron Age, as was implie...

Abstract Reference materials (RMs) with well-characterised composition are necessary for reliable quantification and quality control of isotopic analyses geological samples. For in situ Rb-Sr analysis silicate minerals via laser ablation inductively coupled plasma tandem mass spectrometry (LA-ICP-MS/MS) a collision/reaction cell, there is general lack mineral-specific matrix-matched RMs, which ...

A total of four muddy–fine sand deposits attached to the undersides cobles and boulders three Claudiconcha japonica fossils were collected determine formation age conglomeratic beachrock developing at Sasebo, Nagasaki prefecture. The geology surveyed coast consists non-limestone rocks. Radiocarbon dating using Accelerator Mass Spectrometry (AMS14C dating) for samples was conducted beachrock. It...

This data article contains mineralogical and chemical data from mineral accretions sampled from rock art shelters in the Kimberley region of north west Australia. The accretions were collected both on and off pigment and engraved rock art of varying styles observed in the Kimberley with an aim of providing a thorough understanding of the formation and preservation of such materials in the conte...

Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...

Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS) is classically used in U-Pb dating to measure U and Pb isotopic concentrations. Recently, it has become frequently fission-track (FT) chronometry too. As an advantage, the FT double will enable efficiently determining crystallization ages thermo-tectonic history concurrently as samples volume, analytical time, efforts, cost...
