MC-ICP-MS测定岩石标准物质的钒同位素组成
Vanadium Isotope Composition of Rock Reference Materials by MC-ICP-MS
摘要
Abstract
In order to ensure the accuracy and precision of data during the analysis of vanadium isotopes,and facilitate the comparison of data among laboratories internationally,considering the shortage of inventory for the commonly used reference materials from the United States Geological Survey(USGS),seven reference materials(JA-1,JB-3,JB-1b,JGb-1,GBW07105,GBW07123,and GBW07454)with unreported vanadium isotope composition were selected from the Geological Survey of Japan(GSJ)and the Institute of Geophysical and Geochemical Exploration,Chinese Academy of Geological Sciences(IGGE)and their vanadium isotopes were measured using MC-ICP-MS.Among these reference materials,the gabbro reference material JGb-1 has the highest δ51V value of-1.05‰±0.08‰,and the andesite reference material JA-1 has the lowest δ51V(-0.34‰±0.06‰).The δ51V values of the other reference materials range from-0.72‰to-0.81‰,all falling within the MORB range.The reporting of the vanadium isotopic composition of these reference materials in this article will enrich the database of vanadium isotopic research and contribute to the future study of vanadium isotopes in more fields.The BRIEF REPORT is available for this paper at http://www.ykcs.ac.cn/en/article/doi/10.15898/j.ykcs.202405280123.关键词
