Intrasample osmium isotope disequilibrium in young volcanic rocks

This dataset includes data from the three tables that appearsw in the manuscript titled "Intrasample osmium isotope disequilibrium" by Bharadwaj and Sharma (202x). Table 1 is the procedural blanks; Table 2 is the Os-isotope data for Hawaiian basalts and Mohns Ridge basalt; Table 3 is the Re and Mo concentrations for leachates of these samples. The Os-isotope data are a result of a new technique of investigating intrasample Os isotope heterogeneity in young volcanic rocks, currently being revised for publication at GCA. These data are used to interpret the origin of labile, radiogenic Os release during acidic bromide leaching of these samples. The Os-isotope data in conjunction with previously published geochemical data is used to draw inferences about the mantle sources of the corresponding locations that the samples are derived from.本数据集包含Bharadwaj与Sharma于202x年完成的题为《样品内锇同位素不平衡（"Intrasample osmium isotope disequilibrium"）》的手稿中的三张表格数据。其中表1为流程空白样数据；表2为夏威夷玄武岩与莫恩斯脊玄武岩的锇同位素（osmium isotope）数据；表3为上述样品浸出液中的铼（Re）与钼（Mo）浓度数据。该锇同位素数据源于一项用于探究年轻火山岩样品内锇同位素非均质性的新技术，目前该技术的相关研究成果正提交至《地球化学与宇宙化学学报》（Geochimica et Cosmochimica Acta，GCA）进行修订以待发表。本数据集被用于阐释上述样品在酸性溴化物浸出过程中，易活动型放射性锇释放的成因机制。结合此前已发表的地球化学数据，该锇同位素数据可用于推断样品来源区域对应的地幔源区特征。
