地球化学分析数据_全球橄榄石主微量元素数据集

该数据集包括近年发表的高精度橄榄石主、微量元素和部分寄主岩石的全岩主微量数据，主要元素有Fe、Mg、Si、Ni、Mn、Ca、Zn、Co、V、Ti、Sc、Li、P、Cr、Al等。其中分了四个数据表，其中：Barnes2022的数据表收集了全球27893个高精度橄榄石分析数据，其中包括了全球铜镍矿床的橄榄石主量元素数据，火山岩橄榄石斑晶的主量元素和少量微量元素。Wang2021数据表主要包括地幔橄榄岩、阿拉斯加型岩体、蛇绿岩、层状岩体。Mao2022数据表包括新疆铜镍矿床的橄榄石主量与微量元素。Su2019数据表主要为地幔和地壳橄榄岩的橄榄石数据，包括主量元素和部分微量元素。这些数据的分析方法为高精度电子探针和LA-ICP-MS。

This dataset comprises recently published high-precision major and trace element data of olivine, as well as whole-rock major and trace element data for selected host rocks. The major elements involved include Fe, Mg, Si, Ni, Mn, Ca, Zn, Co, V, Ti, Sc, Li, P, Cr, Al, among others. This dataset is divided into four data tables, detailed as follows:
1. The Barnes2022 table collects 27,893 high-precision olivine analytical data points from across the globe, including major element data of olivine from global Cu-Ni deposits, as well as major element and minor trace element data of olivine phenocrysts in volcanic rocks.
2. The Wang2021 table primarily contains olivine data from mantle peridotites, Alaskan-type intrusions, ophiolites, and layered intrusions.
3. The Mao2022 table includes major and trace element data of olivine from Cu-Ni deposits in Xinjiang.
4. The Su2019 table mainly provides olivine data from mantle and crustal peridotites, including major elements and some trace elements.
The analytical methods applied to these data are high-precision electron microprobe and LA-ICP-MS.
