Silicon isotope data for bulk meteorites and terrestrial standards

This data set contains bulk rock, mass-dependent and mass-independent 29Si/28Si and 30Si/28Si silicon isotope compositions of carbonaceous chondrites, non-carbonaceous chondrites (ordinary and enstatite), Martian, ureilite, eucrite, diogenite angrite, and pallasite meteorites as well as terrestrial rock standards. All data is reported relative to the NBS-28 quartz standard. Data collection was performed using a multi-collector inductively coupled plasma mass spectrometer following purification of silicon by ion exchange chromatography.本数据集包含碳质球粒陨石、非碳质球粒陨石（普通球粒陨石与顽火辉石球粒陨石）、火星陨石、顽火无球粒陨石、钙长辉长无球粒陨石、古铜辉石无球粒陨石、钛辉无球粒陨石、橄榄陨铁以及地球岩石标准物质的全岩（bulk rock）硅同位素组成，具体为质量分馏型与非质量分馏型的29Si/28Si及30Si/28Si比值。所有数据均以NBS-28石英标准（NBS-28 quartz standard）作为参考基准进行报告。数据采集流程为：先通过离子交换色谱法（ion exchange chromatography）纯化硅元素，随后采用多接收器电感耦合等离子体质谱仪（multi-collector inductively coupled plasma mass spectrometer）完成测试。
