LA-ICP-MS Trace Element Data for Sulfide Minerals from Mid-Ocean Ridge Hydrothermal Vent Field

Dataset for: Fluid evolution in mid-ocean ridge vent systems: Implications from trace element variation during chimney growth to mound buildup.
This dataset presents in situ geochemical data for sulfide minerals collected from the Xunmei Hydrothermal Field on the Mid-Atlantic Ridge. The data comprises electron probe micro-analyzer (EPMA) measurements for major elements and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) measurements for trace elements. The data is organized into three sheets: data, errors, and limits of detection (LOD).
Note: Values that are bolded represent measurements below the LOD. These values have been replaced by half the LOD value to facilitate statistical analyses and data visualization.

数据集主题：洋中脊喷口系统的流体演化——从烟囱生长至热液丘形成过程中微量元素变化的指示意义

本数据集收录了采自大西洋中脊寻美热液场（Xunmei Hydrothermal Field）的硫化物矿物原位地球化学数据。该数据集包含主量元素的电子探针显微分析仪（electron probe micro-analyzer, EPMA）测试数据，以及微量元素的激光剥蚀-电感耦合等离子体质谱（laser ablation-inductively coupled plasma-mass spectrometry, LA-ICP-MS）测试数据。数据分为三个工作表：实测数据、误差数据与检测限（limits of detection, LOD）。

备注：加粗数值代表低于检测限的测试结果。为便于开展统计分析与数据可视化，此类数值已替换为对应检测限值的一半。
