This paper reports the results from a second characterisation of 91500 zircon, including data electron probe microanalysis, laser ablation inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS), secondary ion mass (SIMS) and fluorination analyses. The focus this initiative was to establish suitability large single zircon crystal for calibrating in situ analyses rare earth elements oxygen isotopes, as well provide working values key geochemical systems. In addition extensive testing...
We introduce and propose zircon M257 as a future reference material for the determination of U‐Pb ages by means secondary ion mass spectrometry. This light brownish, flawless, cut gemstone specimen from Sri Lanka weighed 5.14 g (25.7 carats). Zircon has TIMS‐determined, mean isotopic ratios (2s uncertainties) 0.09100 ± 0.00003 206 pb/ 238 U 0.7392 0.0003 207 235 U. Its age is 561.3 0.3 Ma (unweighted mean, uncertainty quoted at 95% confidence level); system concordant within decay constants....

Three synthetic reference glasses were prepared by directly fusing and stirring 3.8 kg of high‐purity oxide powders to provide materials for microanalytical work. These have andesitic major compositions are doped with fifty‐four trace elements in nearly identical abundance (500, 50, 5 µg g −1 ) using or element solutions, named ARM‐1, 2 3, respectively. We further document that sector‐field (SF) ICP‐MS (Element Element XR) is capable sweeping seventy‐seven isotopes (from 7 Li 238 U, a total...
A natural smoky quartz crystal from S handong province, C hina, was characterised by laser ablation ICP ‐ MS , electron probe microanalysis ( EPMA ) and solution to determine the concentration of twenty‐four trace ultra elements. Our main focus on T i quantification because increased use this element for titanium‐in‐quartz itani Q thermobarometry. Pieces a uniform growth zone 9 mm thickness within were analysed in four different LA laboratories, three laboratories one solution‐ laboratory....
The combination of scanning electron microscope–cathodoluminescence (CL), fluid inclusion analysis and high-resolution probe microanalysis Al, Ti, K Fe in vein quartz has yielded results permitting a greater understanding the complex mineralisation Central Oyu Tolgoi Zesen Uul porphyry-style deposits, southern Mongolia. These data demonstrate relationship between precipitation, dissolution ore deposition as mineralising chemistry changed through time. Four major generations are identified...
Sets of 20 soda ash, 16 lime and 23 wood ash glasses mainly from excavations in Europe were analysed by microprobe LA–ICP-MS for 61 elements are presented as average concentrations with standard deviations. Concentrations sodium, potassium magnesium allow the major glass type to be identified. Specific compositions raw materials production indicate certain sources, technical processes ages. Heavy minerals etc. quartz sands contain rare earth (REE) crustal fractionations that different three...

This study documents the chemical and textural responses of zircon in Elba igneous complex, with particular reference to 7- 7.8-Ma-old Monte Capanne pluton relation its coeval volcanic counterpart (Capraia), using BSE imaging quantitative electron microprobe analyses. The displays multiple field geochemical evidence for magma mixing. samples we have investigated (including monzogranitic, mafic enclave dyke samples) display similar textures are associated an extremely large range trace minor...
Significance The most concerning example of ongoing climate change is the rapid Arctic sea-ice retreat. While just a few years ago ice-free summers were expected by end this century, current models predict to happen 2030. This shows that our understanding changes in cryosphere limited, which largely due lack long-term observations. Newly discovered long-lived algae growing on seafloor and forming tree-ring–like growth bands hard, calcified crust have recorded centuries history. show that,...
To expand the newly developed ARM glasses as reference materials for in situ microanalysis of isotope ratios and iron oxidation state by a variety techniques such SIMS, LA‐MC‐ICP‐MS EPMA, we report Li‐B‐Si‐O‐Mg‐Sr‐Nd‐Hf‐Pb data Fe 2+ /ΣFe these glasses. The were mainly obtained TIMS, MC‐ICP‐MS, IR‐MS wet‐chemistry colorimetric techniques. quality was cross‐checked comparing different or results from laboratories using same technique. All three appear to be homogeneous with respect...
We investigated rhodoliths (coralline red algae) from a subtropical locality in the Gulf of California ( Lithothamnium crassiusculum ) and subarctic Newfoundland glaciale for their potential as paleoenvironmental archives using microanalytical geochemical techniques to measure variations δ 18 O, Mg, Ca. Rhodoliths are potentially well suited recorders shallow water signals because they (1) have worldwide distribution tropics polar regions, (2) long lived decades centuries, (3) display...
Microtextures and zoning patterns in sanidine phenocrysts from the phonolitic Laacher See Tephra (Germany) were investigated order to constrain processes occurring magma chamber before eruption. The unit is chemically zoned has been inferred represent product of eruption an inverted, layered chamber. Samples various levels deposit investigated. We used a combination textural studies (optical microscopy back-scattered electron (BSE) imaging), microprobe (EMP) analysis major, minor trace...
