Supplementary Information Materials for the G-Cubed submission by Zakharov et al.

This is an upload for the purposes of review at the G-Cubed journal by AGU. The supporting information is provided for the MGL opal-CT, as well as the results of the SIMS and EMPA measurements. The Secondary Ion Probe Mass Spectrometry (SIMS) measurements are included as the .xslx table (Data Set S1) with analytical conditions, raw measurements and VSMOW-calibrated values. The Electron Microprobe (EMPA) analyses are provided in the .xslx file (Data Set S2). The Data Set S2 is separated by tabs for individual sample. Images feature the analyzed areas, including petrographic image, reflected light and the SIMS points.本上传资料为提交至美国地球物理联合会（American Geophysical Union，AGU）旗下《G-Cubed》期刊的审稿材料。本次提供的补充材料涵盖MGL蛋白石-CT（opal-CT）相关内容，以及二次离子探针质谱法（Secondary Ion Probe Mass Spectrometry，SIMS）与电子探针显微分析（Electron Microprobe，EMPA）的测试结果。其中，二次离子探针质谱法（SIMS）的测试数据以.xslx表格（数据集S1）形式呈现，包含分析条件、原始测试数据与经维也纳标准平均海水（Vienna Standard Mean Ocean Water，VSMOW）校准后的数值。电子探针显微分析（EMPA）的分析结果存储于.xslx文件（数据集S2）中，该文件按单个样品以制表符分隔。配套图像展示了所有分析区域，包括岩相照片、反射光图像以及SIMS测试点位图。
