Constrained host rock ChemCam data for the Bradbury Group, Murray formation and Stimson formation

Geochemical dataset of major element oxides analysed by the NASA Curiosity rover ChemCam instrument of the Bradbury Group, Murray formation and Stimson formation in Gale crater. These data were used to generate the constrained bulk rock compositions for the Bradbury Group, Murray formation and Stimson formation in Bedford et al. (2019; https://doi.org/10.1016/j.gca.2018.11.031) and Bedford (2019) thesis chapters 3, 4 & 5.This dataset includes all ChemCam observation point major element oxide data that analysed host rock from sol 14 to 2139. This dataset excludes ChemCam calibration targets, observation points that have targeted obvious alteration features, soils float and drill dumps. This dataset also does not contain analyses with total sum of oxides outside the range 95-105 wt% to reduce contamination from open system alteration features.

本数据集为NASA Curiosity火星车ChemCam仪器在盖尔撞击坑布拉德伯里组、默里层和斯蒂姆森层进行的地球化学主要元素氧化物分析数据。这些数据被用于构建布拉德伯里组、默里层和斯蒂姆森层的限定性岩石总成分，相关成果收录于Bedford等人（2019年；https://doi.org/10.1016/j.gca.2018.11.031）以及Bedford（2019年）的论文第3、4、5章。该数据集涵盖了从第14个火星日到2139个火星日的ChemCam观测点主要元素氧化物数据，分析对象为主岩。数据集排除了ChemCam校准目标、针对明显蚀变特征的观测点、土壤浮选物和钻探废弃物。此外，为降低开放系统蚀变特征带来的污染，本数据集不包含氧化物总量超出95-105 wt%范围的分析数据。
