Summary: Insufficient sampling of periodic signals can lead to aliasing, which causes erroneous variations in measured element concentrations. A fire control circuit has been developed to align laser firing with the measurement cycle of the mass spectrometer to lessen or eliminate aliasing. This technique can maintain measurement precision even when the extent of mixing between individual laser pulses is reduced by an order of magnitude.

Summary: Previous studies have shown that haemodialysis patients have an increased risk of trace element imbalances. In this study, both serum and whole blood concentrations of a wide panel of trace elements in haemodialysis patients were determined and compared with those of a control group. The results indicate that chronic haemodialysis may affect intra- and extracellular blood compartments differently, leading to significant trace element imbalances.

Summary: Bastnasite is commonly found in different types of rock formations, and its U-Th-Pb ages can indicate the age of mineralization. The lack of suitable in situ analysis reference material is currently a major challenge for bastnasite U-Th-Pb geochronology. This study used glass NIST 610 as an external calibration reference to evaluate the matrix effects in determining U-Pb and Th-Pb ages in bastnasite, and found that with the addition of water vapor, accurate and precise U-Th-Pb ages of bastnasite can be obtained using LA-ICP-MS analysis.

Summary: The study investigates the Ca isotopic composition of arc lavas from the Tonga rear arc and Mariana arc in the western Pacific. Results show that carbonates released from the altered oceanic lithosphere do not significantly modify the Ca isotopic composition of the mantle wedge, possibly due to a limited Ca budget in slab fluids or homogenization effect of variable delta Ca-44/40 in slab fluids.

Summary: Studies suggest that the Shuram Excursion event in the late Ediacaran period is geologically and geochemically related to igneous processes in the Doushantuo Formation in South China. These findings imply that ancient carbonate rocks, subjected to decarbonation during subduction, melting, and eruption related to the breakup of the Rodinia supercontinent, contributed to the Shuram Excursion event. This igneous model may provide a connection between the deep and shallow carbon cycles of the Earth.

Summary: The remobilization of sedimentary carbonate in subduction zones affects arc volcanism emissions and the Earth's climate over geological timescales. High-pressure reaction experiments show that most limestone remains stable and stored in the subarc lithosphere, leading to massive carbon storage in convergent margins. Although some limestone may undergo melting, the majority of the carbon flux is influenced by the stable storage of limestone.

Summary: The proposed method utilizing laser ablation solution sampling multicollector inductively coupled plasma mass spectrometry for isotopic analysis of boron in natural liquids and digested samples is fast and efficient without the need for prior purification. By using a bracketing standard and strategic dilution, the method achieves high sensitivity, eliminates memory effects, and shows good accuracy and precision in measuring delta B-11 in various sample matrices. The advantages of simple sample preparation, fast analysis, and minimal chemical reagent use make this method a promising approach for isotopic analysis in geological and other samples.

Summary: The knowledge of elemental composition in geological samples is crucial for Earth science research. A new NH4HF2 digestion method was proposed to dissolve geological samples, but it required long evaporation and re-dissolution times. By using a PTFE beaker and microwave heating method, the evaporation and re-dissolution times were significantly shortened, reducing the time consumed for sample evaporation by a factor of approximately 26.

Summary: Green-core clinopyroxene (GCPX) widely occurs in diverse magmas and various tectonic settings. The in-situ trace element and Pb isotopic compositions of GCPXs in the Feixian and Sihetun primitive basalts from the eastern North China Craton were investigated to explore their potential origins. The results suggest that GCPXs can be simply formed through the two common magmatic processes of continental basaltic magmas, crystallization differentiation, and crustal assimilation.

Summary: The Tanz zircon megacrysts from Tanzania exhibit uniform U-Pb ages, O isotopes, and Zr isotopes, making them suitable as reference materials for microbeam analysis. However, they show a wide distribution of Hf isotope compositions, which hinders their potential as a reference material for microbeam analysis. These features suggest that the Tanz zircon megacrysts could be used as a primary reference material for U-Pb ages and Zr-O isotopes.
